The pump is used to pump water at 25°C from a low reservoir to a high reservoir
through a cast iron piping which is 800 m in total length, 15 cm diameter. The difference
between the water levels in the reservoirs is 8 m. Neglecting all losses except friction
find the power input to the pump. Use the information given to assume the friction factor
and confirm that it is indeed correct.
