Steam flows steadily through an adiabatic turbine. The inlet conditions of the steam are 10 MPa, 450°C, and 80 m/s, and the exit conditions are 10 kPa, 92% quality, and 50 m/s. The mass flow rate of the steam is 12 kg/s.
Determine:
(a) the change in kinetic energy
(b) the power output
(c) the turbine inlet area
Answer:
a) The change in Kinetic energy, KE = -1.95 kJ
b) Power output, W = 10221.72 kW
c) Turbine inlet area, \(A_1 = 0.0044 m^2\)
Explanation:
a) Change in Kinetic Energy
For an adiabatic steady state flow of steam:
\(KE = \frac{V_2^2 - V_1^2}{2} \\\).........(1)
Where Inlet velocity, V₁ = 80 m/s
Outlet velocity, V₂ = 50 m/s
Substitute these values into equation (1)
\(KE = \frac{50^2 - 80^2}{2} \\\)
KE = -1950 m²/s²
To convert this to kJ/kg, divide by 1000
KE = -1950/1000
KE = -1.95 kJ/kg
b) The power output, w
The equation below is used to represent a steady state flow.
\(q - w = h_2 - h_1 + KE + g(z_2 - z_1)\)
For an adiabatic process, the rate of heat transfer, q = 0
z₂ = z₁
The equation thus reduces to :
w = h₁ - h₂ - KE...........(2)
Where Power output, \(W = \dot{m}w\)..........(3)
Mass flow rate, \(\dot{m} = 12 kg/s\)
To get the specific enthalpy at the inlet, h₁
At P₁ = 10 MPa, T₁ = 450°C,
h₁ = 3242.4 kJ/kg,
Specific volume, v₁ = 0.029782 m³/kg
At P₂ = 10 kPa, \(h_f = 191.81 kJ/kg, h_{fg} = 2392.1 kJ/kg\), x₂ = 0.92
specific enthalpy at the outlet, h₂ = \(h_1 + x_2 h_{fg}\)
h₂ = 3242.4 + 0.92(2392.1)
h₂ = 2392.54 kJ/kg
Substitute these values into equation (2)
w = 3242.4 - 2392.54 - (-1.95)
w = 851.81 kJ/kg
To get the power output, put the value of w into equation (3)
W = 12 * 851.81
W = 10221.72 kW
c) The turbine inlet area
\(A_1V_1 = \dot{m}v_1\\\\A_1 * 80 = 12 * 0.029782\\\\80A_1 = 0.357\\\\A_1 = 0.357/80\\\\A_1 = 0.0044 m^2\)
A plant engineer wishes to know which of two types of lightbulbs should be used to light a warehouse. The bulbs currently used cost $45.90 per bulb and last 14,600 hours before burning out. The new bulb ($60 per bulb) provides the same amount of light and consumes the same amount of energy but lasts twice as long. The labor cost to change a bulb is $16.00. The lights are on 19 hours a day, 365 days a year. If the firm's MARR is 15%, what is the maximum price (per bulb) the engineer should be willing to pay to switch to the new bulb? (Assume that the firm's marginal tax rate is 40%.)
The plant engineer should be willing to pay a maximum price of $30.89 per bulb to switch to the new bulb and still achieve a 15% MARR considering the given costs, labor, and operating hours.
To determine the maximum price per bulb the plant engineer should be willing to pay to switch to the new bulb, we need to compare the costs of using the current bulb versus the new bulb over their respective lifetimes.
Let's start with the current bulb:
- Cost per bulb: $45.90
- Lifetime: 14,600 hours
- Labor cost to change a bulb: $16.00
- Annual operating hours: 19 hours/day * 365 days/year = 6,935 hours/year
To calculate the total cost of using the current bulb over its lifetime, we need to consider the cost of bulbs and the labor cost for replacements:
Total cost = (Cost per bulb + Labor cost per replacement) * (Total replacements over the lifetime)
Total cost = ($45.90 + $16.00) * (14,600 hours / 6,935 hours/year)
Total cost = $61.90 * 2.103 ≈ $130.11
Now let's consider the new bulb:
- Cost per bulb: $60.00
- Lifetime: 2 * 14,600 hours = 29,200 hours
The maximum price per bulb the engineer should be willing to pay for the new bulb is the price at which the total cost of using the new bulb equals the total cost of using the current bulb:
Maximum price per bulb = Total cost of using the current bulb / (Lifetime of the new bulb / Annual operating hours)
Maximum price per bulb = $130.11 / (29,200 hours / 6,935 hours/year)
Maximum price per bulb = $130.11 / 4.211 ≈ $30.89

In a fixed orifice tube system the ___________________ prevents liquid refrigerant from entering the compressor.
In a fixed orifice tube system, the orifice tube itself prevents liquid refrigerant from entering the compressor.
The orifice tube is a small, fixed-size opening located in the liquid line of the air conditioning system. Its purpose is to regulate the flow of refrigerant into the evaporator coil. When the high-pressure liquid refrigerant passes through the orifice tube, it undergoes a sudden drop in pressure. This drop in pressure causes the refrigerant to rapidly change from a high-pressure liquid to a low-pressure mixture of liquid and vapor.
The orifice tube is designed to only allow the passage of this low-pressure mixture, while blocking the entry of liquid refrigerant. This is important because the compressor is designed to compress only vapor, not liquid. If liquid refrigerant were to enter the compressor, it could cause damage and decrease the efficiency of the system.
Therefore, the orifice tube plays a crucial role in a fixed orifice tube system by preventing the entry of liquid refrigerant into the compressor. It achieves this by regulating the flow of refrigerant and allowing only the low-pressure mixture of liquid and vapor to enter the evaporator coil. This helps maintain the proper functioning and efficiency of the air conditioning system.

roundoff errors are errors during computer calculations, two theoretically equal numbers (e.g. sin (pi) and 0) can differ slightly, causing an equality or inequality test to fail.
What are the different types of errors in computers?
The three primary types of programming errors are logical errors, syntax errors, and semantic errors.
The most difficult error categories to spot are logical errors. The program "misbehaves" in some way as a result of them, producing an incorrect output of some sort rather than crashing or simply ceasing to function. The null reference is one kind of logical blunder.
In contrast to logical errors, syntax errors in computer programming occur out of order in the language used by the computer. Any syntax mistakes you encounter when using compiled languages will be discovered at compile time and must be fixed before the application will execute.
Incorrect "program statements" are known as semantic errors. Although there are various definitions of what constitutes a semantic error, we are arguing here that while semantic errors also produce nothing at all, logic errors produce inaccurate data.

#5 Air undergoes an adiabatic compression in a piston-cylinder assembly from P1= 1 atm and Ti=70 oF to P2= 5 atm. Employing ideal gas model with constant specific heat capacity ratio (Y), determine the work and heat transfer per unit mass if y = 1.5. (15 points)
Answer:
The work transfer per unit mass is approximately 149.89 kJ
The heat transfer for an adiabatic process = 0
Explanation:
The given information are;
P₁ = 1 atm
T₁ = 70°F = 294.2611 F
P₂ = 5 atm
γ = 1.5
Therefore, we have for adiabatic system under compression
\(T_{2} = T_{1}\cdot \left (\dfrac{P_{2}}{P_{1}} \right )^{\dfrac{\gamma -1}{\gamma }}\)
Therefore, we have;
\(T_{2} = 294.2611 \times \left (\dfrac{5}{1} \right )^{\dfrac{1.5 -1}{1.5 }} \approx 503.179 \ K\)
The p·dV work is given as follows;
\(p \cdot dV = m \cdot c_v \cdot (T_2 - T_1)\)
Therefore, we have;
Taking air as a diatomic gas, we have;
\(C_v = \dfrac{5\times R}{2} = \dfrac{5\times 8.314}{2} = 20.785 \ J/(mol \cdot K)\)
The molar mass of air = 28.97 g/mol
Therefore, we have
\(c_v = \dfrac{C_v}{Molar \ mass} = \dfrac{20.785}{28.97} \approx 0.7175 \ kJ/(kg \cdot K)\)
The work done per unit mass of gas is therefore;
\(p \cdot dV =W = 1 \times 0.7175 \times (503.179 - 294.2611) \approx 149.89 \ kJ\)
The work transfer per unit mass ≈ 149.89 kJ
The heat transfer for an adiabatic process = 0.

jet propulsion is the usual means of locomotion in water for
Jet propulsion is the normal means of locomotion in water for several aquatic animals such as squids, octopuses, and jellyfish, as well as some fish species such as tuna and eels.
The process involves the release of water under pressure, which propels the organism in the opposite direction. The propulsion can be generated from either a part of the body or a specialized organ. Squid and octopuses employ a siphon that permits the water to escape in a manner that creates thrust.
In the case of jellyfish, their bell-shaped bodies contract, squeezing water out and providing movement. Additionally, several fish species such as eels and tuna employ jet propulsion by allowing water to escape from small, rapidly-moving holes called branchial openings. In this way, they generate thrust and swim in the opposite direction, and they can even change the speed and direction of their movement. As a result, jet propulsion is one of the most common means of locomotion for aquatic animals.

If the rod is heated uniformly to115 oC, determine the length and the diameter of this rod to the nearest micron at the new temperature if the linear coefficient of thermal expansion of steel is 12.5 x 10-6 m/m/oC. What is the stress on the rod at 115oC.
Explanation:
thermal expansion ∝L = (δL/δT)÷L ----(1)
δL = L∝L + δT ----(2)
we have δL = 12.5x10⁻⁶
length l = 200mm
δT = 115°c - 15°c = 100°c
putting these values into equation 1, we have
δL = 200*12.5X10⁻⁶x100
= 0.25 MM
L₂ = L + δ L
= 200 + 0.25
L₂ = 200.25mm
