Chapter 12, Problem 6P
A 1-m3 tank contains air at 0.1 MPa absolute and 20°C. The tank is pressurized to 2 MPa. Assuming that the tank is filled adiabatically and reversibly, calculate the final temperature of the air in the tank. Now assuming that the tank is filled isothermally, how much heat is lost by the air in the tank during filling? Which process (adiabatic or isothermal) results in a greater mass of air in the tank?

A piston cylinder contains 1.25 kg water at 25°C with a constant load on the
piston such that the pressure is 300 kPa. A nozzle in a line to the cylinder is
opened to enable flow to the outside atmosphere at 100 kPa and 25°C. The
process continues until 85% of the initial mass has flowed out. At this point, the
temperature of water increased by 10°C. Assume that the process is done in an
