Question

A pumping pumping 5,000 kg of water per minute to a height of 12 find the power of the engine at 30% of energy is wasted

Answer 1

Answer:

514000 kg metre

Explanation:

(5000x12x60)kg.m/sec is required but losses are 30%

so we need

5000x12x60/0.70 kg.m/sec

=360000/0.7

=514000 kg metre
