Question

motor pump lifts 30 kg of water per minute to a height of 6 m what is the power of motor

Answer 1

power=m×g×h/t
P=30×10×6/60
P=1800÷60
P=30

Answer 2

Answer:

29.4 watts

Explanation:

Weight of the water, motor pump can lift = 30kg (Given)

Height to which water is raised = 6m  (Given)

Equation of power -

Power = Energy/ Time

P= mgh/t

Substituting the values in equation -

P = 30×9.8×6/60. ( 1 min = 60 sec )

P = 30×98/100

P = 2940/100

P = 29.4 watt

Therefore, the power of motor after lifting the water is 29.4 watts.
