420 (feet^3) = 3 141.81818 US gallons
90 cubic feet equates to 673.24675 US gallons of liquid propane.
To convert cubic feet to gallons of propane, you first need to know the specific gravity of propane. On average, the specific gravity of propane is around 0.504. Therefore, 1400 cubic feet of propane would be approximately 702 gallons (1400 cubic feet / 7.48 gallons per cubic foot).
Propane has a density of about 4.2 pounds per gallon. So, 17 pounds of propane would be approximately 4.05 gallons. Since 1 gallon is equivalent to 0.133681 cubic feet, 17 pounds of propane would be roughly 0.54 cubic feet.
AnswerOne Gallon of LPG (liquefied petroleum gas) will expand to 35.79 cubic feet of propane gas at 1 atmosphere of pressure.
Propane has a density of about 4.24 pounds per gallon. Therefore, to convert 20 pounds of propane to gallons, you would divide 20 by 4.24, which equals approximately 4.72 gallons of propane.
First, what is a "natural gas thermal unit"? Are you talking about a therm? And what is liquid propane gas? How can it be a liquid and a gas? Are you talking about liquid propane, which is the fuel in your barbeque grill? That stuff is in liquid form because it's pressurized. When it comes out of the tank, it turns back into a gas, so one would imagine that your so-called "natural gas thermal unit" would apply. But let's assume you meant "therm." A therm is a unit of energy that is equal to 100 thousand BTUs (British Thermal Units). That is about the amount of heat energy liberated by 100 cubic feet (Ccf) of natural gas. But propane has an equivalent energy capacity of about 2500 BTUs per cubic foot, so that translates to 250,000 BTUs per Ccf -- two and half times greater than the rule of thumb I just stated!! -- which is 2.5 therms per Ccf. So, I guess the question would becomes "What amount of gaseous propane -- at standard temperature and pressure -- is equivalent to one gallon of liquid propane?" The way I figure it, one gallon of liquid propane will produce about 36.6 cubic feet of gas.1 So, a 20-pound tank (which holds 4.1 gallons of liquid propane gas) is equal to about 150 cubic feet (or 1.5 Ccf) of gaseous propane. ______________ 1. And the way I figured it is this: Propane can liberate about 2500 BTUs per cubic foot. We also know it can liberate 91,600 BTUs per liquid gallon. So I divided 91.6E3 by 2.5E3 to get 36.6 cu.ft./gal.
Probably cubic inches. Gallons would be possible.
I assuming 25 cu-ft (cubic feet). 34.6 cubic feet of propane vapor equals one gallon of liquid propane. So, 25/34.6 = 0.72 gallons. Depending on the size of the tank, 25 on the gauge will be 25 percent of the total capacity of the tank. A 250 gallon tank will have about 62 gallons. The gauges are in 10 percent increments, so each number represented on the guage ex: 10,20,30,40,50,60,70,80,90, represents 10 percent of otal tank capacity. In a 250 gallon tank 10 would equal 25 gallons, 20 would equal 50 gallons and 30 would equal 75 gallons. Likewise in between these numbers would be 5 or whatever it appears to be closer to above or below 5.
One gallon of propane weighs 5 pounds. The tank would hold 60 gallons.
My guess would be 7.48 gallons since that is how many gallons of water is in a cubic foot
To convert cubic yards to gallons, you can use the following conversion factor: 1 cubic yard is equal to 201.974 gallons. This means that you would multiply the number of cubic yards by 201.974 to get the equivalent volume in gallons.
The volume of 200 gallons of propane at 20 degrees will depend on the pressure at which the propane is stored. Propane expands and contracts with temperature and pressure changes, so you would need to know the pressure in order to calculate the volume accurately.
