LPG tank outlet pressure

[madvb]

Does anyone know what a typical vapor pressure at the outlet of a 500-1000 gallon propane storage tank is....after it has been regulated down? I assume that the propane tank has a pressure regulator on it. I have a 1000-gallon propane tank on site that will feed 3 buildings. Each building will have a separate pressure regulator. I'm trying to size the pipe sizes from the propane tank to the buildings, but not sure what a typical outlet pressure is on the tank.

Each tank has its own pressure regulator that is installed by the manufacturer correct? I wonder if this outlet pressure from the tank is set by the standards/codes or can be specified by the engineer when the tank is purchased?

Thanks.

Call the people that sell the LPG. they know more about than anyone. They are the people on the hook when you hear the big boom and the bldg goes flying away.

Propane pressure at the supply to appliances is usually at 11" wc (water column), which is less than 1/2 psi. This would be the setting on your building regulator. The regulator on your tank would be set to less than 10 psi.
