Answers
The Structured What if Technique (SWIFT) is a decision analysis tool that helps explore the impact of different scenarios on a system or process. It involves systematically changing variables and observing the resulting effects to gain insights into possible outcomes.
SWIFT is a powerful tool used in various fields, including engineering, project management, and risk assessment. It enables decision-makers to make informed choices by quantitatively evaluating different what-if scenarios. The technique follows a structured approach to systematically examine the consequences of altering one or more variables.
Here's an example to illustrate SWIFT: Let's consider a manufacturing company that produces electronic devices. They want to assess the impact of different production volumes on their costs and profits. Using SWIFT, they would identify the key variables that influence production costs, such as raw material prices, labor expenses, and overhead costs.
They would then create a structured model that captures the relationships between these variables and the overall production costs. By systematically altering each variable within a range of values, they can observe how changes in production volume affect costs and profits.
A diagram can be used to visualize the process. It would typically show the different variables involved, their relationships, and the flow of information. Each variable would have associated ranges or values that are altered during the analysis. The resulting data can be used to generate insights and make informed decisions based on the observed outcomes.
In summary, the Structured What if Technique (SWIFT) is a systematic decision analysis tool that allows for the exploration of various scenarios and their effects on a system or process. By systematically changing variables and observing the resulting outcomes, decision-makers can gain valuable insights to make informed choices.

Determine the position of 200 t of cargo to be loaded (from amidships) to ensure the ship floating in even keel condition after the loading completed.
Answers
Answer:
4.2019 mts , 4.598 mts
Explanation:
center of flotation = 2 m fwd.
MCTC = 120 tonnes
Determine the position of 200 t of cargo to be loaded
first step : determine the change trim = trimming moment / MCTC
= 134 * 1 / 120 = 0.11 mts
∴ бtf = 0.11 * ( 2/100 ) = 0.0022 mts ( given that the ship trims forward )
бtf = - 0.0022 mts
also ; бTa = 0.0019 mts ( + due to increase in draught )
determine the Final position
Ta = 4.2 ( draught at AP ) + бTa
= 4.2 + 0.0019
= 4.2019 mts

Answers
1. The equivalent capacitance between terminals a-c is 2.4 μF
2. The equivalent capacitance between terminals b-c is 6μF
3. The equivalent capacitance between terminals c-d is 12 μF
What is a capacitance?Capacitance is the ability for a device to store charge
1. How to find the equivalent capacitance betwee terminals a-c?Given that the capacitance bewteen terminals a-c = a-b + b-c
Now, the capacitance between terminals b-c are in parallel.
So, for capacitances in parallel, we add their capacitances to get the equvalent capacitance.
So, the equivalent capapcitance between b-c is C = 1 μF + 2μF + 3µF = 6μF
Now C is in series with the capapcitance between terminals a-b.
Since they are in series, their equivalent capapcitance C' is
1/C' = 1/4μF + 1/C
= 1/4μF + 1/6μF
= (3 + 2)/12 μF
1/C' = 5/12 μF
C' = 12/5 μF
= 2.4 μF
So, the equivalent capacitance between terminals a-c is 2.4 μF
2. How to find the equivalent capacitance betwee terminals b-c?To find the equivalent capacitance between terminals b-c, we see that the capacitance between terminals b-c are in parallel.
So, for capacitances in parallel, we add their capacitances to get the equvalent capacitance.
So, the equivalent capapcitance between b-c is C = 1 μF + 2μF + 3µF = 6μF
So, the equivalent capacitance between terminals b-c is 6μF
3. How to find the equivalent capacitance betwee terminals c-d?Since there is only one capacitor between terminals c-d, the equivalent capacitance is equal to the value of that capacitor which is 12 μF

How do I find v0 using Kirchhoff's laws and Ohm's law? The answer is 25V but I'm confused about how to get that.
Answers
Answer:
25 V
Explanation:
It is convenient to use Kirchoff's current law (KCL), which tells you the sum of currents into a node is zero. The node of interest is the top left node.
The currents into it are ...
20 mA + (-5 -Vo)/(2kΩ) -(Vo/(5kΩ)) = 0
20 mA -2.5 mA = Vo(1/(2kΩ) +1/(5kΩ)) . . . . add the opposite of Vo terms
(17.5 mA)(10/7 kΩ) = Vo = 25 . . . volts . . . . divide by the coefficient of Vo
_____
You will notice that the equation resolves to what you would get if you drew the Norton equivalent of the voltage source with its 2k impedance. You have two current sources, one of +20 mA, and one of -2.5 mA supplying current to a load of 2k║5k = (10/7)kΩ. KCL tells you the total current into the node is equal to the current through that load (out of the node).

Answers
a) (i) The kinetic energy rate in ft.lbf/s is 0.00771
(ii) kinetic energy being transported by the methanol in the pipe is 1.40 x 10⁻⁵ hp
b) Additional energy is dissipated into other forms. The larger part is heat energy, but also dissipated in light, sound and vibrations.
What is kinetic energy?
The ability of an object to do work by virtue of its motion.
The mass flow rate expressed as
m= 3.00 gal.mm x 1000/264.17L/gal x 0.792 kg/L x 2.20462 / 60= 0.330 lb/s
The velocity is determined by the continuity equation
u= Q/A =[ 3.00 x 35.3145/(264.17x60) ] / π (1/12)²/4
u = 1.225 ft/s
The rate of kinetic energy transport is
K.E = 1/2 x (0.330) x (1.225)² = 0.00771 ft-lb/s
Thus, the kinetic energy rate in ft.lbf/s is 0.00771
The rate of kinetic energy in hp is
K.E = 0.00771 x 1.341 x 10⁻³ /0.7376
K.E = 1.40 x 10⁻⁵ hp

In order of decreasing size (largest listed first), sedimentary grain sizes include __.
A. clay, sand, silt, and gravel
B. gravel, sand, clay, and silt
C. sand, gravel, silt, and clay
D. gravel, sand, silt, and clay
E. gravel, silt, sand, and clay
Answers
The correct order of decreasing size for sedimentary grain sizes is D) gravel, sand, silt, and clay.
Grain size is an important characteristic of sedimentary rocks, and it affects their appearance, texture, and properties. Sedimentary grains can range from very small (clay-sized particles) to very large (gravel-sized particles). The order of decreasing grain size is determined by the settling velocity of each grain size in water. Gravel-sized particles settle the fastest, followed by sand, silt, and clay. Therefore, sedimentary rocks that are composed of larger grains (like gravel) are typically deposited in high-energy environments, such as near rivers, while sedimentary rocks with smaller grains (like clay) are typically deposited in low-energy environments, such as deep ocean basins.

If the old radiator is replaced with a new one that has longer tubes made of the same material and same thickness as those in the old unit, what should the total surface area available for heat exchange be in the new radiator to achieve the desired cooling temperature gradient
Answers
Answer: hello some parts of your question is missing attached below is the missing information
The radiator of a car is a type of heat exchanger. Hot fluid coming from the car engine, called the coolant, flows through aluminum radiator tubes of thickness d that release heat to the outside air by conduction. The average temperature gradient between the coolant and the outside air is about 130 K/mm . The term ΔT/d is called the temperature gradient which is the temperature difference ΔT between coolant inside and the air outside per unit thickness of tube
answer : Total surface area = 3/2 * area of old radiator
Explanation:
we will use this relation
K = \(\frac{Qd }{A* change in T }\)
change in T = ΔT
therefore New Area ( A ) = 3/2 * area of old radiator
Given that the thermal conductivity is the same in the new and old radiators
Two circular rods support the 3800 lb weight of a space heater in a warehouse. each rod has a diameter of 0.375 in and carries 1/2 of the total load. compute the stress in the rods
Answers
The stress in the rods will be 17,140 psi.
The stress in the rods can be calculated by taking the total load of 3800 lbs and dividing it by twice the cross-sectional area of each rod.
With a diameter of 0.375 in, this gives us an area of 0.1103 in2 for each rod. This means that each rod carries 1900 lbs, which produces an axial stress of 17,140 psi.
This is a considerable amount of stress and highlights how important it is to use rods with sufficient strength to safely support such weight while maintaining structural integrity.

Answers
(a) The local acceleration term in the equation of motion (LA) for the x-direction is given by -2Hσ²e^(kz)cos(kx - σt).
(b) The advective acceleration term in the equation of motion (AA) for the x-direction is zero.
The given fluid velocity components in Cartesian coordinates are u = 2Hσe^(kz)cos(kx - σt) and v = 0, w = 2Hσe^(kz)sin(kx - σt), where x represents the horizontal coordinate, z represents the vertical coordinate, and t represents time.
In order to find the expressions for the local acceleration term (LA) and the advective acceleration term (AA) in the equation of motion for the x-direction, we differentiate the x-component of velocity twice with respect to time.
The local acceleration term (LA) represents the acceleration of fluid particles due to the changing velocity field within the fluid. To calculate LA in the x-direction, we differentiate the x-component of velocity with respect to time twice. The first derivative with respect to time gives us the partial derivative of u with respect to time, which is -2Hσ²e^(kz)sin(kx - σt). Taking the second derivative with respect to time gives us the local acceleration term in the x-direction: -2Hσ²e^(kz)cos(kx - σt).The advective acceleration term (AA) represents the acceleration of fluid particles due to the change in velocity as they move through the fluid. In this case, the x-component of velocity does not vary with time, i.e., ∂u/∂t = 0. Therefore, the advective acceleration term in the x-direction (AA) is zero.In summary, the local acceleration term (LA) in the x-direction is given by -2Hσ²e^(kz)cos(kx - σt), while the advective acceleration term (AA) in the x-direction is zero.

Determine (a) the net radiation heat transfer between the two plates per unit surface area of the plates (b) compare the result to that without the shield. (c) temperature of the radiation shield in steady operation
Answers
The net radiation heat transfer between the two plates per unit surface area of the plates with shield and without shied are respectively; 2282.76 W/m² and 9766.75 W/m²
How to find the net radiation heat transfer?We are given;
Temperature 1; T₁
Temperature 2; T₂
Temperature 3; T₃
Emissivity 1; ε₁ = 0.3
Emissivity 2; ε₂ = 0.7
Emissivity 3; ε₃ = 0.2
The net rate of radiation heat transfer with a thin aluminum shield per unit area of the plates with shield is;
Q'₁₂ = σ(T₁⁴ - T₂⁴)]/[((1/ε₁) + (1/ε₂) - 1) + ((1/ε₃,₁) + (1/ε₃,₂) - 1)]
Q'₁₂ = 5.67 * 10⁻⁸(900⁴ - 300⁴)/[((1/0.3) + (1/0.7) - 1) + ((1/0.15) + (1/0.15) - 1)]
Q'₁₂,shield = 2282.76 W/m²
The net rate of radiation heat transfer with a thin aluminum shield per unit area of the plates with no shield is;
Q'₁₂,no shield = σ(T₁⁴ - T₂⁴)]/((1/ε₁) + (1/ε₂) - 1))
Q'₁₂,no shield = 5.67 * 10⁻⁸(900⁴ - 300⁴)/[(1/0.3) + (1/0.7) - 1)]
Q'₁₂,no shield = 9766.75 W/m²
Then the ratio of radiation heat transfer for the two cases becomes;
Q'₁₂,shield/Q'₁₂,no shield = 2282.76/9766.75 = 0.2337 or 4/17
