Calculating Pressure needed to lift dump valve assembly
Calculating Pressure needed to lift dump valve assembly
(OP)
Hello everyone,
I work for a manufacturing firm that designs oilfield equipment. I have the following question.
I am to find the length of a propane fluid column needed to lift a dump valve assembly that weighs 62.4 lbs.
I was given the following information to work with:
Propane Liquid
density of liquid propane = 4.23 lb/gal
Dfloat assembly = 10 inches (hollow on the inside)
Dvessel = 24 inches
I was given no length of either the vessel or the float tube assembly.
Is this a solvable question given the data and how would one go about to solve it. I assumed standard wall thickness for a 10" diameter pipe (.365 in)

RE: Calculating Pressure needed to lift dump valve assembly
If acting against the float then it is 62.4 lbs/area of 10" float to obtain pounds/sq in.
Then use density of propane and calculated pressure in eq P=dens*g*h to calculate h.
However more importantly is what kind of pressure is on the vessel to maintain your C3 liquid.

The pressure of the vessel is at 1440 psi.
