If the power of an engine is known and the amount of time that the engine exerts this power is known, what can be calculated?

1 answer:

4 0

The work done by the engine in a given time.
Power is the time rate of change of energy, (which is another name for work, both measured in Joules)
So power = energy/time, with units of Joules/second.
Since you know energy per time, if you know the amount of time you can multiply power by time to get energy (work).

How many cubic feet are in a 55-gallon drum?

san4es73 [151]

1 gallon = 231 cubic inches
1 cubic foot = 1728 cubic inches

   (55 gal) x (231 in³/gal) x (1 ft³/1728 in³)

   = (55 x 231 / 1728) ft³

   = 7.352 cubic feet (rounded)
