How many pounds of western subbituminous coal would be needed to heat the house (house requires 1,000,000 BTU), with a 60% efficient furnace?
Subitiminous coal = 10,750 BTU/lb
1,000,000 BTU
____________ = 93.02 lb of coal.
10,750 Btu/lb
And I am not exactly sure how to take into account the 60% efficiency:
Take 93.02 / 0.6 = 155.0 lb coal, needed to heat the house. Is that correct?
