Question:
A large, externally insulated hydrogen liquid storage tank made of stainless steel has just been drained and the walls and residual gas are at 36 °R (the atmospheric boiling point of hydrogen). The pressure is 1 atm. The tank is connected to a supply of high-pressure hydrogen gas at 70 °F and very rapidly pressurized to 115 psi. The tank is then held at this pressure by allowing additional gas to enter until the gas and walls are at the same temperature. What is this temperature?
Data: Tank volume: V = 10 ft3; wall mass = 286 lb; assume that the hydrogen is ideal with Cp = 2.6 Btu/lb°R, independent of temperature. The heat capacity of (316) stainless steel is cp = 0.109 + 5.66*10-5*T (cal/g°C) in the temperature range between 200 °C and 1,000 °C. Assume that the temperature dependence of the heat capacity extends to the temperature range .
