In a closed system with a mobile border, a wet vapor with X = 1 is contained. The system undergoes heating keeping the plunger at rest, however the pressure and temperature change to 2MPa and 800 ° c, respectively. Subsequently, the heating process continues at constant pressure until the system reaches a temperature of 1300 ° c, generating an expansion process.
a) estimate the initial pressure of the system
b) calculate the work done by the steam
c) calculate the total heat transferred to the water vapor
d) represent the process on a T-v diagram

Consider a regenerative vapor power cycle with two feedwater heaters, a closed one and an open one, and reheat. Steam enters the first turbine stage at 12 MPa, 560 °C, and expands to 1.5 MPa. Some steam is extracted at 1.5 MPa and fed to the closed feedwater heater. The remainder is reheated at 1.5 MPa to 440 °C and then expands through the second-stage turbine to 0.3 MPa, where an additional amount is extracted and fed into the open...

In a closed, isolated system of particles, forces internal to the system do not change the motion of the system as a whole. The velocity of the center of mass of such a system is unchanged unless the system is impacted by some net external force. In this context, and with the aid of a single illustration, explain what is meant by a) internal force, and b) external force. c) Explain why internal forces have no effect on the system’s...

The capacity of a propane vapor-compression refrigeration system is 8 tons. Saturated vapor at 0°F enters the compressor, and superheated vapor leaves at 120°F, 180 lbf/in.2 Heat transfer from the compressor to its surroundings occurs at a rate of 3.5 Btu per lb of refrigerant passing through the compressor. Liquid refrigerant enters the expansion valve at 85°F, 180 lbf/in.2 The condenser is water-cooled, with water entering at 65°F and leaving at 80°F with a negligible change in pressure. Determine (a)...
