A friction-free, weighted piston-cylinder device contains 2.0 kg of water in a mixed state at a pressure of 150kPa and a quality of 0.60. As it sits there, heat is lost until the mixture becomes entirely a saturated liquid. How much heat is lost in the process? Thanks!

Air in a cylinder-Piston device undergoes a cyclic process. Initially, the air is at P-5 [MPa) and T-350 [C]. Process 1 to 2 is an isothermal expansion from 5 (MPa) to 1 [MPa). Process 2 to 3 is a polytropie compression to 5 [MPa) with a polytropic exponent n=1.3. The cycle gets completed by a constant pressure process from the state 3 to 1. Air properties are R 0.287 [Kj/Kg. K] and k=1.4 and the mass of air in cylinder...

Ammonia in a piston-cylinder assembly undergoes two processes in series. At the initial state, pi- 120 lbfin? and the quality is 100%. Process 1-2 occurs at constant volume until the temperature is 100°F. The second process, from state 2 to state 3, occurs at constant temperature, with Q23-98.9 Btu, until the quality is again 100%. Kinetic and potential energy effects are negligible. For 2.2 lb of ammonia, determine (a) the heat transfer for Process 1-2, in Btu, (b) the work...

A piston-cylinder device contains water which is initially at 100 C and 20 bar. It undergoes two processes. The first process is isothermal and the second process is constant volume. The final condition is a saturated vapour at 2 bar. Calculate heat transfer and work (both in kJ/kg) for each process.
