Problem 79P

Applying the Energy Balance

One-half kg of Refrigerant-22 is contained in a piston-cylinder assembly, initially saturated vapor at 5 bar. The refrigerant undergoes a process for which the pressure-specific volume relation is pv = constant to a final pressure of 20 bar. Kinetic and potential energy effects can be neglected. Determine the work and heat transfer for the process, each in kJ.

Solution

Step 1 of 3

Consider a of Refrigerant is contained in a piston-cylinder assembly, initially saturated at . The pressure-specific volume relation is in which the refrigerant undergoes a process , we need to find out the work and the heat transfer for the process.
