We have been given this problem through university and I am stumped!!!

Consider a propane tank that initially contains 5 L of liquid propane at the environment temperature of 20 degrees C.

If a hole develops in the connecting tube of the propane tank and the propane starts to leak out, determine the temperature of the propane when the pressure in the tank drops to 1bar under equilibrium conditions.

Also determine the total amount of heat transfer from the environment to the tank to vaporize the entire propane in the tank under equlibrium conditions to 20 degrees C.

(Specific heat capacity of liquid propane 2.4 kJ/kg.K vapour propane 1.7 kJ/kg.K).

I also have access to the saturated properties table of propane.


Any help would be much appreciated!! :) Thanks

If only we could calculate the mass of the gas in the tank. mL is the answer. Where L is the latent heat of vaporization.

If any one finds a mistake in this please put forward.
