A piston- cylinder assembly with initial volume of 80 liters contains 4kg of R-134a at a pressure of 160 kPA (state 1). Then R-134a expands to a volume of 0.4916m^3 at constant pressure (state 2). Finally, the pressure of R-134a becomes 100kPa (state 3). During the process 2 >3, volume increases as PV^1.01= constant.
A) Draw a T- v diagram. Determine all three states and indicate them on constant pressure (T-v) lines.
B) Determine the volume occupied by the vapor phase at state 2.
C) Determine the total work done during the entire process ( 1>2>3).
D) Determine the total heat transfer during the entire process.
