Refrigerant 134a in a cylinder-piston assembly is at 240 kPa with a quality 15% and then as a result of heat added the quality increases to 45%, what is the change in volume per one unit of mass (m3/kg)? The piston is assumed to move freely but it is sealed tight that does not allow mass exchange.

Refrigerant 134a, initially (state 1) a saturated liquid at -80C, is contained in a piston-cylinder assembly. The water undergoes a process to the corresponding saturated vapor (state 2), during which the piston moves freely in the cylinder. The change of state is brought about by heating the water as it undergoes an internally reversible process at constant pressure and temperature. If the mass of the refrigerant is 0.1 kg, determine (a) heat transfer using first law of thermodynamics in kJ...

Thermodynamic In a piston-cylinder air at 100 kPa and 15°C undergoes the following cycle. First, it is compressed isentropically to a compression ratio of 20. Then 1800 kJ/kg of heat is transferred to the air at constant pressure. Afterwards the air expands isentropically. In the last step, heat is removed at constant volume until the air reaches its original state. Assuming air behaves as an ideal gas and with Cp and Cv independent of temperature, determine the: (a) pressure and...
