Question
As shown in the figure below, Refrigerant 134a is contained in a piston-cylinder assembly, initially as saturated vapor. The refrigerant
is slowly heated until its temperature is 155°C. During the process, the piston moves smoothly in the cylinder.
For the refrigerant, evaluate the work, in kJ/kg.
W/m = i
kJ/kg.
Patm = 1 bar
Piston
Refrigerant 134a
