Pressure Power?

Question

Hydrologic pressure in a subterranean aquifer pushes 900 lb of water 80 ft to the surface through a natural spring in 2.0 minutes. How much power is utilized?

Answer 1

power is energy per unit time. The energy to move the water is mgh so the power is mgh/t or g x 900lbs x 80ft/2 minuets, where g is the gravitational constant

Covert units to some standard unit of power
