The length of time a propane tank lasts on a hot air balloon depends on several factors. These factors include the size of the tank, the operator's discretion, and wind. Most last several hours.
It all depends on the amount of fuel you have, most hot air balloons carry 1-2 fuel tanks. On average a hot air balloon burns 25 Gallons of propane an hour, and average fuel tank is a 10 Gallon fuel tank, sometimes 15 Gallons, meaning roughly 45 minutes to an 60 minutes, sometimes its a cool day, you'll require less fuel for more heat, it will last up to an 90 minutes. However, larger balloons carry more fuel, and can stay in the air longer.
forever probably, unless a meteor hits it.
6 to 8.5 hours during space walk
the first phase is takeoff, then the two side rockets come off, last the big orange tank comes off.
The Columbia orbiter was 122.17 feet long. The entire Space Shuttle (which includes the external fuel tank and solid rocket boosters) is184 feet long. All space shuttles and orbitals seem to be the same length.
About 120psi for a 16 oz propane tank
The propane will last until the tank is empty.
They use propane to heat regular air in the balloon. \The canopy of the balloon only holds heated air, the propane is held in a tank and is only used to create heat.
That depends on the output level of the propane.
1 gallon of Propane ~= 4.23 lbs ~= 91500 Btus 1 lbs of Propane ~=22000 Btus 20 lb tank of propane holds approx 4 gallons of propane (366000 BTUs) Your grill will last 366000 BTUs/ Grill BTU output hrs
A 20 pound propane tank holds 4.1 gallons of LP which equates to about 0.016 cubic meters. If your heater burns 3 m3 per hour the tank will last about 19 seconds. If you meant .0003 then it will last 51.73 hours.
Surely it depends on your rate of usage-what appliances you run from it
Depends on usage of fireplace. Have propane tank topped off monthly to figure out how much gas being used. Either that, or wait until tank is empty.
I believe portable barbecue grills last as long as the propane tank you have, possibly buy a few extra of them, just to make sure they last through the whole entire football game.
10 years
A 60 gallon tank?
As long as the heater is made for propane.
