Afurnace is rated 4000 btu per hour. how many foot pounds of energy are released in one hour? - 5.1 foot pounds- 2,456,000 foot pounds- 0.2 foot pounds- 3,112,000 foot pounds

To solve this we are going to use a conversion factor. We know that 1 BTU per hour is approximately 778 foot-pounds of energy per hour, so our conversion factor will be: .

Now we just need to multiply 4000 BTU by our conversion factor:


We can conclude that the furnace released 3,112,000 foot pounds of energy in one hour.
