Carry out the preliminary thermodynamic design of a system that isothermally fills an initially evacuated, rigid, cylindrical tank with air at 20.0°C to 20.0 MPa with a minimum amount of entropy production. The tank is 0.250 m in diameter and 1.50 m high.
Assume the air behaves as a constant specific heat ideal gas.
Discuss the technology and economics of how the tank is maintained isothermal during the filling process. Note that there will beentropy production in the pipes and valves used to connect the tank to the air supply.
