The power of a motor pump is

$2\ kW$ . How much water per minute the pump can raise to a height of

$10\ m$ ? (Given g = 10 m s–2)

The formula to calculate the Work done ( $W$ ) is,

$W\ =\ m \times g\ +\ h$
$W\ =\ m \times g$
$W\ =\ m \times \frac{g}{h}$
$W\ =\ m \times g \times h$

Power is calculated by:

$Power\ =\ Work\ done \times Time$
$Power\ =\ \frac{Work\ done}{Time}$

The pump can raise

$kg$ of

$water\ per\ minute$ .
