An insulated, rigid tank with a volume of 10ft3 is connected by a valve to a supply line containing steam at 500 psia and 800 degrees F. The tank is initially evacuated. The valve is opened long enough to fill the tank to a pressure of 500 psia. Determine;
a) The final temperature of the steam in the tank, in degrees F
b) The final mass of the steam in the tank, in lbm.
