Question

Assume the following: 1) He is a noble gas that follows the ideal gas law with R = 2.0769 kJ/kg-K and a constant Cp = %R; 2) The wall leak

can be approximated as a capillary tube; 3) The flow through capillary being slow, kinetic energy can be neglected. What is the mass of He leaked into the outer chamber? (B) (15 Pts) What is the uniform temperature maintained inside the He tank during the process? (C) (20 Pts) What is the amount of heat loss to the surroundings from the outside chamber during the process? (D) (10 Pts) What is the mass of He left inside the tank at the time the leak stopped?
