Determine the power of the pump, which delivers 3000 kg of water to a height of 5 m for 5 minutes.

To find the power of the specified pump, we use the formula: N = A / t = m * g * h / t.

Variables and constants: m – mass of supplied water (m = 3000 kg); g – acceleration due to gravity (g ≈ 10 m / s2); h is the height of the water supply (h = 5 m); t – time spent by the pump (t = 5 min = 300 s).

Calculation: N = m * g * h / t = 3000 * 10 * 5/300 = 500 W.

Answer: The power of the indicated pump is 500 W.
