LPG weight to volume unit
Forum rules
Dear convert-me.com forum visitors,
Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.
All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on convert-me.com FaceBook page
Thank you for being with us and sorry for any inconveniences this could caused.

LPG weight to volume unit

What is the volume in cubic feet of 100 lbs. of LPG contained in a cylinder?. Approximate size of cylinder is 12 inches diameter and 54 inches long. Consider an average temperature of 80 degrees farenheit.

The tough part was finding density at 80 °F instead of the standard 60 °F. This table http://www.elyenergy.com/pdf/CO37.pdf gives 0.03257 ft^3/lb at 80 °F. So your 100 lbs occupies 3.257 ft^3 (ignoring the amount as vapor above the liquid).
The volume of a cylindrical tank is (pi/4)*(d^2)*h but your dimensions are in inches. Converting to feet,
(pi/4) * 1^2 * 54/12 = 3.53 ft^3.
So tank is pretty full. I don't know what the requirements are for expansion volume in the tank for warmer temperatures, but this seems "close". NOTE: The volume calculations assume these are inside dimensions. If they are outside dimensions a correction for wall thickness is required.

Based on the previous answer, and given the following condition, can you find out how much time would last a 100 lbs LPG cylinder, if we have an LPG power generator running with a fuel consumption as follows:
1/2 Load ........... 55.6 ft^3/hr
Full Load ........... 86.4 ft^3/hr
Required fuel pressure is 11"-14" of water column
1/2 Load ........... 55.6 ft^3/hr
Full Load ........... 86.4 ft^3/hr
Required fuel pressure is 11"-14" of water column
