A piston-cylinder assembly has a liquid-vapor mixture of R-134a, with initial total mass of 3 kg, total volume of 0.12 m3 and a temperature of 10°C. The refrigerant then undergoes two processes in series: constant-temperature process followed by a constant- pressure process. At the end of the constant-pressure process, the pressure is 140 kPa and the R-134a is all saturated liquid. The constant temperature process is adiabatic while the constant-pressure process is not. Neglect kinetic and potential effects.
a. Solve for the initial quality of the liquid-vapor mixture of R-134a.
b. Determine the work and heat transfer for the constant-temperature process, in kJ.
c. Determine the work and heat transfer for the constant-pressure process, in kJ.

A mass of 3 kg of saturated liquid-vapor mixture of water is
contained in a piston-cylinder device at 175 kPa. Initially, 2 kg
of the water is in the liquid phase and the rest is in the vapor
phase. An electrical heater is in operation, and the piston rises
until it hits a set of stops, which are set at double the initial
volume. Electrical heating continues until the pressure reaches 500
kPa. Determine (a) the initial and final temperatures,...

A piston-cylinder assembly contains 2.5 kg of saturated refrigerant
R-134a with a quality of 10 % at 0 °C (State 1). There is a linear
spring mounted on the piston such that when the mixture is heated
the pressure reaches 1000 kPa with a volume of 70 L just as the
piston touches the stop (State 2). The system is then heated
further until a pressure of 1200 kPa is reached (State 3). a) Find
the volume of the refrigerant...

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...
