What is the limit of liquid propane in a tank?

[QUOTE="tpv, post: 6248843, member: 544989"] My humblest apologies. I made a terrible mistake. The above equation dV = 1.003 dT is incorrect. The incompatibility of the units should have told me this equation was wrong. The proper equation is: dV/Vo = 0.003 (1/degree K) dT (where V = volume, Vo = initial volume of the tank, and T = Temperature) This makes the volume of the tank fall out of the end result (as expected). And the final equation is much cleaner: dP = (95.7 psi/degree K) dT With this equation, the internal pressure of the liquid propane will hit 1000 psi after only a 9 degree rise in temperature, or at 35 C. In summary, From 0 C to 26 C, the liquid expands from 92% to 100%. At 26 C, the liquid fills the tank, and the pressure is 135 psi. from 26 to 35 C, the liquid pressure increases from 135 psi to 1000 psi. There is a real and definite risk of a propane tank exploding if it is over filled. [/QUOTE]
