That depends on the output level of the propane.
It lasts around 10-12 hours on a 20lb propane tank.
A 20lb propane cylinder typically holds around 4.7 gallons of propane. Propane weighs about 4.2 pounds per gallon, so a 20lb cylinder can hold roughly 17-18 pounds of propane when full.
It depends on the rate of consumption for the individual grill. Size of burners, number of burners, heat of flame required, manufacturer ... it's like asking how many days will a box of cornflakes last until it's eaten. Too many variables.
That would depend on too many things that are no listed. Need to know what the desired temperature is.. What the BTU rating of the heater is, what the efficiency rating is, what the R value of the structure is.
I inject, season & cover my 20lb turkey with aluminum foil & bake all night @ 225*. At around 5-6am I uncover the turkey then I put it on 350* for 2 more hours..equalling about 8 hours total. My turkey is always a hit!-juicy, tender & perfectly golden brown:)
Type your answer here... there are around 91,600 BTUs in a gallon of propane. The standard BBQ sized bottle of propane contains 11 pounds of propane. Propane weighs about 4.2 pounds per gallon, so that 11 pounds of propane is about 2.5 gallons in its liquid state. That means there is 91,600 BTUs/Gal times 2.5 gallons so a BBQ sized tank of propane contains about 2.3 million BTUs. If your BBQ has a 50,000 BTU burner, on high heat, it will last a bit over 4 and half hours of run time.
You can mail up to 5 sheets of 20lb paper with 1 standard postage stamp within the United States.
The amount of propane burned in a propane fireplace can vary based on factors such as the size of the fireplace, its energy efficiency, and how long it is used. On average, a propane fireplace can burn approximately 1 to 2 gallons of propane per hour of operation.
Depends on the size of the burner, if the unit is 5000 btu's ,( probably much smaller), but it makes the math easy that would run a fridge (full throttle) for 20 hours. The flame cycles, so it won't use that non stop. To make it easy., divide the amount of btu's into 93,000 (roughly the btu's in a gallon of propane) and you will have your answer
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
The factors that determine how long a propane generator can run are the size of the propane tank, the size of the generator, the brand of generator, and what is being used under the generator's power.
