The pressure inside a propane tank depends on the ambient temperature of the tank and if Liquid Propane Gas (LPG) is present inside the tank. It has nothing to do with the size of the tank. A 20 lb tank that is not more than 80% full, in an 100 degree F environment, with LPG in it, will have approximately 172 PSIG, just as a 200 lb that is not more than 80% full, in an 100 degree F environment, with LPG in it, will have approximately 172 PSIG.
Examples are: A tank with LPG (no more than 80% full) at 80 degree F with have 128 PSIG, 60 degree F with have 92 PSIG, 30 degree F with have 51 PSIG, and -20 degree F with have 11 PSIG.
This explains the decrease in pressure as you use a large amount of propane from a tank quickly. The tank cools due to the venture effect which drops the temperature of the LPG. The drop in temperature results in a drop in pressure. When the tank warms up, as long as Liquid Propane Gas is still present the pressure will go up.

∙ 12y agoAs long as their is some liquid propane left inside the vessel the psi will change with the temperature.
Makes no difference what size the vessel is, 20lb-1000lb same temperature same pressure.
At 80 deg F the pressure is about 80psi.

∙ 11y agoPropane vapor inside the tank is temperature dependent. It is at 0psi at -40degF as this is the boiling point of propane to about 200psi at 120degF.
Propane is at about 100psi at the room temperature.

∙ 15y agoA 1lb. tank has 197 psi, according to Bernzomatic's website. I assume a 20lb. tank would be the same pressure because it would turn to liquid at the same point.

How many gallons in a 20 lb propane tank?
About 4.1 gallonsPropane is a gas at standard temperature and pressure. A 20-pound tank holds about 4.1 gallons of liquid propane. It's a liquid in the tank because it's under great pressure. 4.2 lb per US gallon5.1 lb per Imperial gallon
How long will 30000 btu heater run on a 23 gallon tank?
The MH80CV, part of the Mr. Heater Contractor Series, is a 30,000-80,000 BTU Propane Convection heater. The MH80CV provides reliable heat for areas up to 1900 sq. feet. It will operate for up to 14 hours on a 20-lb propane tank. The MH80CV features a standing pilot, piezo push-button ignition, and 'insta-lock' chamber for easy assembly. The MH80CV comes ready to use with the included hose and regulator. It operates on a 20-lb or larger propane tank (not included).There are a couple of other factors that may effect the time a 20 pound cylinder will last on a heater. Propane is stored in liquid form in the tank and must evaporate to be used in most heaters. The colder the temperature the propane tank is stored at the lower the pressure is in the tank. As the liquid propane evaporates it cools down the liquid propane still in the tank. As a result at minus -20 you might have a half full twenty pound tank and not have enough pressure to run the heater.
What is the height of a 40lb propane tank?
