|Mar22-11, 09:36 AM||#1| Thermodynamics Problem gas expansion 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 |Apr10-11, 08:33 AM||#2| 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 fo
