Calculate total work input to compressor to charge the tank

Question

Problem

1. Air in a tank is at 300 kPa, 400 K with a volume of 2 m³. A valve on the tank is opened to let some air escape to the ambient to a final pressure inside of 200 kPa. At the same time the tank is heated, so the air remaining has a constant temperature. What is the mass average value of the air leaving, assuming this is an internally reversible process?

2. A supply line is supplied by an insulated compressor that takes in R-134a at 5^oC, quality of 96.5%, and compresses it to 3 MPa in a reversible process. An insulated 2-m³ tank is charged with R-134a from the line, the tank is initially evacuated, and the valve is closed when the pressure inside the tank reaches 2 MPa. Calculate the total work input to the compressor to charge the tank.

The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
