A pump draws 1000 kg of water per minute from a well 12m deep. Then the power of the pump in H.P. unit
would be very nearly equal to ........... (given g = 10 m/s2
)

Given conditions ⇒
Mass of the Water pumped per minutes = 1000 kg.
Height of the well = 12 m.
∴ Energy used in pumping the water = Change in Potential energy
= mgh - 0
= 1000 × 10 × 12 = 120000 J.
Power = Work/Time
= 120000/60
= 2000 W.
To Convert it into Horse Power,
∴ 1 Hp = 746 W.
∴ 2000 W = 2000/746 Hp. = 2.68 Hp.
Hope it help.s
