1300-L rigid tank contains 16 kg of refrigerant-134a vapor at 320 kPa. The refrigerant is cooled until the temperature reached -14oC.
(a) Determine the temperature at which the refrigerant starts to condense.
(b) How much liquid remains in the tank at the end of the process?
(c) Determine the internal energy change for this process.
(d) Show the process on T-? and P-? diagrams.
