Question

With a machine, 500kg of water was raised 50m height in 6 minutes. Its efficiency is 50%
(c) Determine the power of the machine.
(d) If efficiency is increased by 25% then what will be change in spent energy-Analyze mathematically.​

Answer 1

Answer:

the power of the machine is raising 1000 kg of water to 100 metres height in 6 minutes.

if the efficiency will be increased by 25% -

now 100% , after increasing it to 25% it will be 125% and change in energy spend will exactly be 25% more than now.
