A frictionless piston-cylinder device contains a saturated liquid-vapor mixture of water at 373K. During a constant pressure process, 600 kJ of heat is transferred to the surrounding air at 300K. Asa result, part of the water vapor contained in the cylinder condenses. Determine (1) the entropy change of the water, (2) the entropy change of the air (3) the total entropy generation during this process.

A steady flow Carnot cycle uses water as the working fluid. Water changes from saturated liquid to saturated vapor as heat is transferred to it from a source at 250 C. Heat rejection takes place at pressure of 20 kPa. Determine a) the thermal efficiency? b) the amount of heat rejected c) the net work output
In a well-insulated rigid tank which contains 2 kg of a saturated liquid-vapor mixture of water at 200 kPa
In a well-insulated rigid tank which contains 2 kg of a saturated liquid-vapor mixture of water at 200 kPa, 40% of the mass is in the liquid phase. A heater is providing heat to the content of the tank so that all liquid phase converts to vapor phase. Calculate the entropy change of water in this process.

Figure provides steady-state data
for a throttling valve in series with a heat exchanger. Saturated
liquid Refrigerant 134a enters the valve at T1 = 36 degrees Celsius
with a mass flow rate of 0.26 kg/s and is throttled to T2 = -8
degrees Celsius. The refrigerant then enters the heat exchanger,
exiting as saturated vapor with no significant decrease in
pressure. In a separate stream, liquid water enters the heat
exchanger at T4 = 20 degrees Celsius and exits as...

Problem 6.024 SI Two kilograms of water contained in a piston-cylinder sembly, initially saturated vapor at 340 kPa, is condensed at constant pressure to saturated liquid. Consider an enlarged system consisting of the water and enough of the nearby surroundings that heat transfer occurs only at the ambient temperature of 25°C. Assume the state of the nearby surroundings does not change during the process, and ignore kinetic and potential energy effects For the enlarged system, determine the heat transfer, in...
