How long will a 100 lb propane tank last at 30,000 BTU?

What is the estimated duration for a 100 lb propane tank to last when used at a rate of 30,000 BTU per hour? The estimated duration for a 100 lb propane tank to last when used at a rate of 30,000 BTU per hour is approximately 72 hours.

Propane Tank Usage and Duration Calculation

Propane tanks are commonly used to fuel appliances such as heaters, grills, and generators. The duration a propane tank lasts depends on its size and the rate at which it is consumed.

When calculating the duration of a 100 lb propane tank at 30,000 BTU per hour, we first need to determine the total amount of BTUs the tank holds and divide it by the consumption rate.

1. Determine the Total BTUs in a 100 lb Propane Tank:

Propane contains approximately 91,500 BTU per gallon. Since a 100 lb tank holds about 23.6 gallons of propane (1 gallon weighs 4.24 lbs), the total BTUs in a 100 lb tank would be 23.6 gallons x 91,500 BTU/gallon = 2,157,600 BTU.

2. Calculate the Duration:

To find out how long the 100 lb propane tank will last at a rate of 30,000 BTU per hour, we divide the total BTUs in the tank by the consumption rate: 2,157,600 BTU ÷ 30,000 BTU/h = 72 hours.

Therefore, a 100 lb propane tank would last approximately 72 hours when used at a rate of 30,000 BTU per hour.
