Tank A has a volume of 100 liters and contains saturated vapor r-134 at 30C. With the valve open slightly flow enters cylinder B. a pressure of 200kpa is required to lift piston in b. the process ends when the pressue at A drops to 200kPa. during this process all r-134a is at 30c because of heat transfer.
calculate A) work Done b ) Heat transfer
