Refrigerant 134a enters a compressor operating at steady state
assaturated vapor at 0.12mpa and exits at 1.2mpa and 70c at a
masflow rate of 0.108kg/s. as the refrigerant passes through
thecompressor, heat transfer to the surroundings occurs at a of
0.32kj/s. determine at steady state the power input to the
compressor, in kw.

Apiston-cylinder device contains 0.1 m3 of liquid water and 0.9 m3 of water vapor in equilibrium at 800 kpa. heat is transferred at constant pressure until the temperature of water reaches 350 °c. determine (a) the quality of water at the initial state (b) the work associated with this process, (c) the heat associated with this process.
