Margaret is considering an investment that will cost her $500 today. It will pay her $100 at the end of each of the next 12 months, and cost her another $300 one year from todav. Illustrate these cash flows in two cash flow diagrams. The first should show each cash flow element separately, and the second should show only the net cash flows in each period.
Determine the mass fux of air flowing through the nozzle if the receiver exits to the atmosphere. (a) Use equations and (b) use the appropriate table.
oil enters a counter flow heat exchanger at 450 k with a mass flow rate of 10 kgs and exits at 350 k. a separate stream
Assuming the average rate of heat dissipation from people in an exercise room is 525 W determine the rate of heat gain of the exercise room from people and the equipment at peak load conditions.
a distillation column as shown in the figure to the right is a device used to separate components with different
a rigid tank 0.4 m3 contains air at 400 kpa and 30c and is connected by a valve to a piston-cylinder device with zero

Four bolts in the holes shown in the Figure hold the window in place. If the windows are to be installed with their centers at a depth of 3 ft below the surface of the water, determine the force on each of the four bolts.
Water at 100 kPa, 25C is brought to the boiling point in a piston/cylinder with an isobaric process. The heat is supplied by a heat pump with the cold side at the ambient temperature of 25C. Assume that the whole process is reversible and find the wo..
steam at 1 mpa 630.2oc expands in an insulated piston cylinder assembly to 0.01 mpa. determine the maximum work kj done
Using MATLAB/Simulink®, write a computer program to represent the SEIG in its transient state.- What you have to do in order to allow the IG to self-excite again?
In nearly all practical situations, the argument of the exponential term in Equation 7.43 for FR is quite small. Use this fact along with Taylor's series expansion to derive an alternate equation for FR. Determine the range where the alternate equ..
An inventor claims to have developed a Lenoir engine with an isentropic compression ratio of 8.00 to 1 that produces a combustion temperature of 1500.°C when the intake temperature is 20.0°C. Assuming k = 1.40 and that the engine operates on a col..
