Please write equations clearly and table numbers
Refrigerant R-134A is trapped inside a piston-cylinder assembly. The refrigerant undergoes a compression process from a pressure of 400 kPa containing 55% saturated liquid to a final pressure of 600 kPa. During the compression process, a total of 110 KJ/kg of heat is transferred out while the boundaries of the cylinder are maintained at 100°C, which is also the temperature of the surroundings During this process the entropy generation is o.06749 kJ/kg K....

An adiabatic frictionless piston-cylinder device initially contains 4 kg of saturated R-134a liquid at 400 kPa. The refrigerant is then heated using a resistance wire that receives a current of 6 A from a DC power supply for 20 seconds and the volume is increased 100 times. Determine (a) the initial temperature, (b) the final temperature, (c) the change in the specific enthalpy, and (d) the voltage of the power source. Also show the process on the P-v diagram with...

A 2.2-m3 rigid tank initially contains air at 100 kPa and 22°C. The tank is connected to a supply line through a valve. Air is flowing in the supply line at 600 kPa and 22°C. The valve is opened, and air is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. A thermometer placed in the tank indicates that the air temperature at the final state is...

Professor Modyn owns another piston-cylinder device, which initially (State 1) contains 0.236 m3 of saturated water vapor at 400.0 kPa. Heat is now slowly transferred to the steam until the volume doubles. Consider the expansion a two step process. First, constant volume heating occurs until the pressure reaches 500.0 kPa (State 2). Finally, a constant pressure expansion occurs resulting in the doubling of the initial volume (State 3) Note: The IUPAC sign convention for work is used. Work into the...
