Consider a Rankine cycle with saturated steam leaving the boiler at a pressure of 2 MPa and a condenser pres- sure of 10 kPa.
(a) Calculate the thermal efficiency of the ideal Rankine cycle for these operating conditions.
(b) If the net reversible work for the cycle is 0.5 MW, calculate the required flow rate of cooling water supplied to the condenser at 15°C with an allow- able temperature rise of 10°C.
(c) Design a shell-and-tube heat exchanger (one-shell, multiple-tube passes) that will meet the heat rate and temperature conditions required of the con- denser. Your design should specify the number of tubes and their diameter and length.
A heat pump is used to heat a building. The outside air temperature is -10 C and the desired inside temperature is 20.3 C. The heat loss through the walls, ceiling, etc, is 30 kW. Determine the ideal coefficient of performance and the minimum power r..

Calculate the change in free-energy associated with the formation of a critical spherical nucleus in pure liquid nickel that is 200 ºC under cooled. Properties of Nickel: Heat of Fusion 2660 J/cm3; Surface Energy 255x10-7 J/cm2 ; Freezing Temperatur..
an ideal gas with molecular weight of 6.5 kgkgmol is compressed in a reversible manner from 690 kpa and 277 k to a
The cylinder of a turbocharged diesel engine is filled with air at 30.0 psia and 250°F. When the intake valve closes, cylinder volume is 60.0 in3. The piston moves upward un-til cylinder volume is 4.00 in3, at which time pressure is 1100 psia. What ..
Air enters a window air conditioner at 1 atm, 32C, 70% relative humidity at a rate of 2 m^3/min, and it leaves as saturated air at 15C. Part of the moisture in the air that condenses during the process is also removed at 15C. Determine the rates of h..
the maximum power output capability of an engine decreases with altitude because the air density and hence the mass
Estimate the FAD (N.T.P.) of the compressor, and the relative humidity of the air entering the compressor - Select and size a suitable type of machine with regard to output FAD (free air delivered) and quality of air supply.
