A 2kg steam was in a piston cylinder with pressure of 1 MPa and 200°C.Heat transferred isobarically in the cylinder and volume of steam is at 1m3. Find the final temperature of steam, in °C.

Refrigerant R134a in piston cylinder assembly, 200 kPa in initial state pressure and in the form of saturated vapor. It is then reversed and The final pressure is 1000 kPa by being compressed in the adiabatic state change. a) Find the final temperature (°C). b) Find the work done (kj/kg). Note: The changes in kinetic and potential energies will be neglected.

A rigid steel tank contains 0.5 kg R410A at 0°C with a specific volume of 0.01 m³/kg. The whole system is now heated to a room temperature of 25°C. Find the final P and the process heat transfer.

A piston/cylinder has a water volume separated in VA = 0.3 m³ and VB = 0.4 m by a stiff membrane. The initial state in A is 1000 kPa, x = 0.8 and in B it is 1500 kPa and 250°C. Now the membrane ruptures and the water comes to a uniform state at 200°C. What is the final pressure? Find the work and the heat transfer in the process. Po mp cb A:H2O B:H20

A certain ideal gas has a constant R = 38.9 ft-lff/lbm-R with k = 1.4. a) If 3 lbm of this gas undergoes a reversible nonflow constant volume process from 120 psia,740 oF to 140 oF find P2, ∆U, ∆H, Q, Work. b) If the process in “a” had been steady flow find work and ∆S.

A quantity of ideal gas with an initial condition of 0.1 m3 and 735 kPa expands isothermally to 118 kPa. Find the heat transfer during the process.
