In a fixed orifice tube a/c system, the low-pressure cycling switch is typically located in the low pressure line or on the:_______.
In a fixed orifice tube air conditioning (A/C) system, the low-pressure cycling switch is typically located in the low-pressure line or on the accumulator.
The low-pressure line is the refrigerant line that carries the refrigerant from the evaporator (inside the vehicle) back to the compressor (located in the engine compartment). The low-pressure cycling switch is installed in this line to monitor the pressure level of the refrigerant.
The accumulator, also known as the receiver-drier in some systems, is a component that is connected to the low-pressure line. Its primary function is to collect and store excess liquid refrigerant and to remove moisture and debris from the refrigerant stream. The low-pressure cycling switch can also be located on the accumulator.
The purpose of the low-pressure cycling switch is to monitor the pressure in the A/C system and activate or deactivate the compressor based on the preset pressure thresholds. This helps to protect the system from damage caused by low refrigerant levels or other issues.

Explanation:
cubical tank 1 meter on each edge is filled with water at 20 degrees C. A cubical pure copper block 0.46 meters on each edge with an initial temperature of 100 degrees C is quickly submerged in the water, causing an amount of water equal to the volume of the smaller cube to spill from the tank. An insulated cover is placed on the tank. The tank is adiabatic. Estimate the equilibrium temperature of the system (block + water). Be sure to state all applicable assumptions.
Answer:
final temperature = 26.5°
Explanation:
Initial volume of water is 1 x 1 x 1 = 1 \(m^{3}\)
Initial temperature of water = 20° C
Density of water = 1000 kg/\(m^{3}\)
volume of copper block = 0.46 x 0.46 x 0.46 = 0.097 \(m^{3}\)
Initial temperature of copper block = 100° C
Density of copper = 8960 kg/\(m^{3}\)
Final volume of water = 1 - 0.097 = 0.903 \(m^{3}\)
Assumptions:
since tank is adiabatic, there's no heat gain or loss through the wallsthe tank is perfectly full, leaving no room for cooling airtotal heat energy within the tank will be the summation of the heat energy of the copper and the water remaining in the tank.mass of water remaining in the tank will be density x volume = 1000 x 0.903 = 903 kg
specific heat capacity of water c = 4186 J/K-kg
heat content of water left Hw = mcT = 903 x 4186 x 20 = 75.59 Mega-joules
mass of copper will be density x volume = 8960 x 0.097 = 869.12 kg
specific heat capacity of copper is 385 J/K-kg
heat content of copper Hc = mcT = 869.12 x 385 x 100 = 33.46 Mega-joules
total heat in the system = 75.59 + 33.46 = 109.05 Mega-joules
this heat will be distributed in the entire system
heat energy of water within the system = mcT
where T is the final temperature
= 903 x 4186 x T = 3779958T
for copper, heat will be
mcT = 869.12 x 385 = 334611.2T
these component heats will sum up to the final heat of the system, i.e
3779958T + 334611.2T = 109.05 x \(10^{6}\)
4114569.2T = 109.05 x \(10^{6}\)
final temperature T = (109.05 x \(10^{6}\))/4114569.2 = 26.5°

Suppose that a wing component on an aircraft is fabricated from an aluminum alloy that has a plane strain fracture toughness of 29 MPa (26.39 ksi). It has been determined that fracture results at a stress of 101 MPa (14650 psi) when the maximum internal crack length is 7.5 mm (0.2953 in.). For this same component and alloy, compute the stress level at which fracture will occur for a critical internal crack length of 5 mm (0.1969 in.).
Answer:
123.46 MPa
Explanation:
( Aluminum alloy Plane strain fracture toughness = 29 MPa ( 26.39 ksi )
Fracture results at a stress of 101 MPa ( psi )
maximum internal crack length = 7.5 mm ( 0.2953 in )
Compute the stress level at which fracture will occur for a critical internal crack length of 5 mm ( 0.1969 in )
Y = \(\frac{KI_{c} }{\alpha \sqrt{\pi a} }\)
Y = 29 / 101 √π [( 7.5 * 10^-3 ) / 2]
= 29 / 101 √ 0.01178097245 = 29 / ( 101 * 0.1085 )
= 2.65
hence the stress level at which fracture will occur for a critical internal crack length of 5 mm
∝c = \(\frac{KI_{c} }{y\sqrt{\pi a} }\)
Given; y = 2.65 , KIc = 29, a = ( 5 * 10^-3 ) / 2 = 0.0025
hence ∝c = 29 / 2.65 \(\sqrt{\pi *0.0025}\)
= 29 / 0.2349 ≈ 123.46 MPa

The inception of cavitation
Answer:
The overview of the given question is described in the explanation segment below.
Explanation:
Cavitation inception or emergence happens whenever the localized temperature decreases far enough underneath the saturated or dissolved vapor pressure, a quantity determined by the thermal strength or conductivity of the fluid beyond a certain point (temperature).To respond to induce cavitation emergence, the cavitation "bubbles" usually allow a layer on which they could be nucleated.technician a says that brake fluid that is allowed to remain uncovered absorbs water. technician b says that if brake fluid is accidentally spilled on a fender of a vehicle, it can damage the paint. who is correct?
Technician A and Technician B both are correct as brake fluid that is allowed to remain uncovered does absorb water and brake fluid can damage the paint on a vehicle's fender if it is accidentally spilled.
Technician A is correct because brake fluid is hygroscopic, which means it absorbs moisture from the atmosphere. This water can corrode brake parts and lead to failure, as well as increase the fluid's boiling point, leading to brake fade and reduced stopping power.
Technician B is also correct because brake fluid is made up of corrosive materials that can break down paint and other surfaces. If the brake fluid is not cleaned off the fender immediately, it can cause permanent damage to the paint.

one 10-horsepower, 208-volt, 3-phase, continuous-duty, induction type design b motor; one 25-horsepower, 208-volt, 3-phase, continuous-duty, induction type design b motor; and one 30-horsepower, 208-volt, 3-phase, continuous-duty, induction type design b motor are supplied by a single motor branch circuit. calculate the minimum ampacity for the single motor branch-circuit conductors supplying all three motors.
The minimum ampacity for the single motor branch-circuit conductors supplying all three motors is approximately 117.89 Amps. To calculate the minimum ampacity for the single motor branch-circuit conductors supplying all three motors, we need to consider the full load currents of each motor.
For a 3-phase motor, the full load current (FLC) can be calculated using the following formula:
FLC = (Power / (√3 * Voltage * Power Factor * Efficiency))
Given:
Motor 1: 10 horsepower, 208 volts, 3-phase
Motor 2: 25 horsepower, 208 volts, 3-phase
Motor 3: 30 horsepower, 208 volts, 3-phase
We'll assume a typical power factor of 0.8 and efficiency of 0.9 for the calculations.
First, let's calculate the full load currents for each motor:
Motor 1:
Power = 10 horsepower = 10 * 746 Watts = 7460 Watts
FLC1 = (7460 / (√3 * 208 * 0.8 * 0.9)) = 18.14 Amps
Motor 2:
Power = 25 horsepower = 25 * 746 Watts = 18650 Watts
FLC2 = (18650 / (√3 * 208 * 0.8 * 0.9)) = 45.34 Amps
Motor 3:
Power = 30 horsepower = 30 * 746 Watts = 22380 Watts
FLC3 = (22380 / (√3 * 208 * 0.8 * 0.9)) = 54.41 Amps
Now, we can find the minimum ampacity for the single motor branch-circuit conductors by adding the full load currents of all three motors:
Minimum Ampacity = FLC1 + FLC2 + FLC3
Minimum Ampacity = 18.14 Amps + 45.34 Amps + 54.41 Amps
Minimum Ampacity = 117.89 Amps
Therefore, the minimum ampacity for the single motor branch-circuit conductors supplying all three motors is approximately 117.89 Amps.

A stall happens when the smooth airflow over the unmanned airplane`s wing is disrupted, and the lift degenerates rapidly. This is caused when the wing "exceeds its critical angle of attack."
The angle of attack refers to the angle at which the airplane's wing meets the air that is flowing over it. When an airplane actually is taking off, it is lifting the nose up into the air. And, if that nose continues to rise ultimately it reaches a point where the air is not able to smoothly flow over the wing, causing the airplane to drop. And, this is the point when the airplane exceeds its critical angle of attack.
Exceeding the critical angle of attack is known to be a stall. This has no concern with the engine stalling, it just concerns with the wings not producing enough lift to keep the airplane in the air.

Blood pressure is conventionally measured in the dimensions of millimeters in a column of mercury, and the readings are expressed as two numbers, for example, 120 and 80. The first number is called the systolic value, and it is the maximum pressure developed as the heart contracts. The second number (called the diastolic reading) is the pressure when the heart is at rest. In the units of kPa and psi, what is the difference in pressure between the given systolic and diastolic readings? The density of mercury is 13.54 Mg/m3.
Answer:
- the difference in pressure between the given systolic and diastolic readings in KPa is 5.313 KPa
- the difference in pressure between the given systolic and diastolic readings in psi is 0.77 psi
Explanation:
Given the data in the question;
blood pressure reading = 120 and 80 { systolic and diastolic }
To determine the difference in pressure between the two readings, we use the equation as follows;
change in pressure ΔP = p × g × h
where p is mercury density, g is acceleration due to gravity and h is difference of height in mercury column.
Frist,
difference of height in mercury column h = 120 - 80 = 40 mm = 0.04 m
given that; The density of mercury is 13.54 Mg/m³ = 13.54 × 10³ kg/m³
Not that Mg is Megagrams not Milligrams }
we know that g = 9.81 m/s²
so we substitute into our equation;
change in pressure ΔP = (13.54 × 10³) × 9.81 × 0.04
ΔP = 5313.096 kg/m-s² ≈ 5313.096 N/m²
ΔP = 5.313 KPa
Therefore, the difference in pressure between the given systolic and diastolic readings in KPa is 5.313 KPa.
In psi,
ΔP = 5.313 KPa
ΔP = 5313 Pa
ΔP = 5313 pa × ( 1.45 × 10⁻⁴ psi / 1 Pa )
ΔP = 0.770385 psi ≈ 0.77 psi
Therefore, the difference in pressure between the given systolic and diastolic readings in psi is 0.77 psi

: The interior wall of a furnace is maintained at a temperature of 900 0C. The wall is 60 cm thick, 1 m wide, 1.5 m broad of material whose thermal conductivity is 0.4 W/m K. The temperature of the outside surface of the wall is 150 0C. Determine the heat through the wall. Also determine thermal resistance to heat flow.
Answer:
Heat is lost at the rate of 750 J/s or W
The thermal resistance is 1 K/W
Explanation:
interior temperature \(T_{2}\) = 900 °C
wall thickness t = 60 cm = 0.6 m
width = 1 m
breadth = 1.5 m
thermal conductivity k = 0.4 W/m-K
outside temperature \(T_{1}\) = 150 °C
heat through the wall = ?
The area of the wall A = w x b = 1 x 1.5 = 1.5 m^2
Temperature difference \(dt\) = \(T_{2}\) - \(T_{1}\) = 900 - 150 = 750 °C
note that \(dt\) is also equal to 750 K since to convert from °C to K we'll have to add 273 to both temperature, which will still cancel out when we subtract the two temperatures.
To get the heat that escapes through the wall, we use the equation
Q = Ak\(\frac{dt}{t}\)
substituting values, we have
Q = 1.5 x 0.4 x \(\frac{750}{0.6}\) = 750 J/s or W
Thermal resistance \(R_{t}\) = \(\frac{dt}{Q}\)
\(R_{t}\) = 750/750 = 1 K/W

Explanation:
can you suggest a reason for the poor agreement between converted and measured brinell numbers in some cases?
All suggestions for the poor agreement between converted and measured brinell numbers in some cases are mentioned below.
Describe Brinell?Brinell is a method for measuring the hardness of a material, typically a metal, by pressing a hard ball or sphere into the surface of the material and measuring the resulting indentation. The Brinell hardness test is widely used in industry to determine the suitability of a material for a particular application, as well as to monitor the quality of materials during manufacturing.
There could be several reasons for poor agreement between converted and measured Brinell hardness numbers, including:
Surface condition: The Brinell hardness test requires a smooth and flat surface for accurate measurement. If the surface is rough or uneven, it can lead to inaccurate measurements and a poor correlation between the measured and converted values.Test conditions: The Brinell test requires specific testing conditions, such as the load applied, the duration of the load, and the diameter of the ball used for indentation. If these conditions are not strictly controlled, it can lead to inconsistencies and inaccurate measurements.Material properties: The Brinell hardness test measures the resistance of a material to indentation. If the material being tested has variations in composition, microstructure, or other properties, it can lead to inconsistent measurements and poor agreement between measured and converted values.Conversion factors: The conversion from Brinell hardness to other hardness scales, such as Rockwell or Vickers, requires the use of conversion factors. If these factors are not accurate or are not applied correctly, it can lead to poor agreement between measured and converted values.It's important to note that the Brinell hardness test is just one method of measuring hardness, and other tests, such as Rockwell or Vickers, may provide more accurate and reliable results in certain situations.
