Yes. Providing that if the 20lb. tank has a hose hook up that the hose will be long enough to reach the shorter 15lb. cylinder's valve. Also the 15lb. cylinder MUST be within 12 years of manufacture or if it's been recertified within the past 5 years AND have an OPD, (overfill prevention device) style valve. This is easily identified by a triangle shaped handle vs. the old round handles.
Propane burns 91,547 b.t.u.'s an hour per gallon of propane. Depending on the b.t.u. output of the appliance you are running you should be able to calculate how many hours you can use your tank.
4.23 pounds per gallon so, weigh a full cylinder a 15 lb tank cannot hold 15 lbs of fuel propane needs expansion room or the tank will explode i would GUESS just a tad over 2 gallons.
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
This is a list of some of the available smaller size propane tanks: * 20# = 4 gallon * 30# = 7 gallon * 40# = 10 gallon * 60# = 15 gallon * 100# = 25 gallon ...and then there are the larger home tanks ranging from 250, 200, 750 and 1,000 gallons.
Volume = pi*r2*h = 1696.5 cubic feet (approx).
there good if you strap 15 canisters of propane to it and then throw a baby at the propane canister
If 15 liters of propane are completely consumed 90,25 grams of carbon dioxide are produced.
Use a 4-pound hammer and hit it with only a soft blow, repeatedly for about 15 mins.
15% * 18 pound = 2.70 pound.18 - 2.7 = 15.30 poundHowever if you misspelled and actually mean 15 percent of18, then the answer is 2.70 pound. ("off" means 18 minus 15% of 18)
Depending on the size propane tank you have for your grill...normally if you are working with a standard size propane tank that comes with your grill when you buy it we normally will get about 25 BBQs out of it. Until it becomes very light-weight and cold on the outside. Again these 25 BBQs are regular hamburgers, hotdogs and chicken cooking...NOT slow cooking ribs, etc.....for hours at a time. These slow cooking BBQ foods can equal 2-3 regular BBQs!!! Hope this helps!
Liquid PropaneThere will be a TW on the side of the cylinder this is the tare weight the weight of the cylinder empty. (TW 18.5) would be an 18.5 pound empty cylinder. A full cylinder will weigh 20 pounds more than the tare weight. Even with an OPD valve a 20 pound cylinder will still hold 20 pounds 95% of the time. If you exchange your tank they are only putting 15-18 pounds of propane in a cylinder that was designed to hold 20 pounds. If you have your cylinder refilled make sure they weigh it on a scale as they fill it and put twenty pounds in it the OPD SHOULD STOP THE PUMP AT THE SAME TIME THE SCALE TIPS.(The weight of th filling valve must be added usually 4-5 pounds). Also propane is stored in the tank as a liquid you use the vapor from the top of tank in your grill. As the vapor pressure lowers the liquid will boil into vapor when the vapor pressure is gone the cylinder is completely empty.A 20-pound tank contains about 4.1 gallons of LP, which weighs about 17 pounds. (LP has a specific gravity -- at 25 degrees C -- about half that of water.) The next time I run my tank empty, I'll weigh it. But I would be willing to bet it weighs about four pounds.
15% of 10 pounds is 1.5 pounds.
