An engine can pump 30000L of water to a vertical height of 45 m in 10 minutes. Calculate the work done by the machine and its power.
An engine can pump 30,000 L of water to a vertical height of 45 m in 10 min. Calculate the work done by the machine and its power. (density of water = 103 kg/m3)
A pump is used to lift 500 kg of water from a depth of 80 m in 10 s.Calculate:
(a) the work done by the pump,
(b) the power at which the pump works, and
(c) the power rating of the pump if its efficiency is 40%.
