Question

An engine of 10kw power is used to pump water from a tank 100m/s depth what is the quantity of water in km which it can be pump out in 1hour

Answer 1

Answer:

Quantity of water in km which it can be pump out in 1 hour is 36734 kg

Explanation:

Power of the engine is P=10 kW

Depth of tank =100 m

Quantity of water m=?

Time =1 hour =3600 sec

Power= Work done/ time

$P=\frac{mgh}{t}\\10000=\frac{m\times 9.8 \times 100}{3600} \\m=\frac{10000 \times 3600}{980y} \\m=36734 kg$

Quantity of water in km which it can be pump out in 1 hour is 36734 kg
