1 btu = 778 fps {standard statistic}

550 fps = 0.746 kW {standard statistic}

convert your btus as fps to kWs -

1 btu then is 778/550 = (v'2) kW

then v'2(0.746)= 1.4927 kW

so a btu is 1.4927 kW

finally, 50,000 btu = 50,000(1.4927) = 74,635 kW <---- answer!

1 kWh=3412 BTUs, so 50,000 BTUs / 3412 = kwH energy

50,000/3412 = 14.654kwH

1 BTU is the energy needed to raise 1 pound of water, by

1 degree fahrenheit, in 1 hour.

I had 1.55 kW per BTU when its 1.055 kW per BTU. Sorry

so Brice is okay, I'm wrong, he's right!

I checked this conversion. Your answer was

correct. 8)

15 kW applied for 1 hour = 15kWh. 15kWh =50000 BTUs energy which raises 50 gal. water by 100 deg. F in an hour (50 x100=5000) which seems correct by the BTU's definition.
