Question

a pump is needed to lift water through a height of 3m at the rate of 600g.what is the minimum horse power of pump​

Answer 1

Answer:

Given:

Mass = 600 g

Height = 3 m

To find:

Power of pump in Horse-Power.

Concept:

Power is defined as the rate of doing work. In other words , it's the ratio of work done to time taken to do the work.

$\boxed{ \sf{ \green{ \huge{P = \dfrac{work}{time} }}}}$

It's SI unit is "Watt". But it is often expressed in Horse-Power (HP)

1HP = 746 Watt

Calculation:

$P = \dfrac{work}{time}$

$= > P = \dfrac{m \times g \times h}{t}$

$= > P = \dfrac{0.6 \times 10 \times 3}{60}$

$= > P = 0.3 \: watt$

Now we know that 1HP = 746 watt .

$\therefore \: 0.3 \: watt = 0.0004 \: hp$

So final answer is :

$\boxed{ \large{ \sf{ \green{power = 0.0004 \: hp}}}}$
