Answer:

  0.64 kW

Explanation:

The potential energy of a mass (M) at some height (h) is computed from ...

  PE = Mgh

At 1 kg/liter, the available power is the rate at which that energy is available ...

  (490 kg/min)×(1 min/(60 s))×(9.8 m/s²)(8 m) ≈ 640.3 kg·m²/s³

  = 640.3 W

In kilowatts, that is 0.64 kW.
