A steam supply line provides steam at 600 F and 300 psia.

(1) Determine the mass and the temperature of the steam in an insulated piston-cylinder arrangement if sufficient steam is admitted to displace the piston by one cubic foot. The cylinder originally is empty, and the piston main- tains a constant pressure of 100 psia as the steam is admitted to the cylinder.

(2) Determine the mass and temperature of the steam admitted into a rigid tank from the supply line if sufficient steam is admitted to obtain a final pressure of 100 psia. The tank originally was empty and the tank volume is one cubic foot. Compare the results for the rigid tank and for the cylinder operating at constant pressure.
