Asked by POPPY
water is pump from lake by an engine at a height of 5m above the lake surface.
if the water is discharged through a nozzle of radius 7cm with speed of 33m/s calculate the power needed asumming perfect energy conversation in the system.
density of water = 1g/cm^2.
acceleration 10m/s/?

find the volume of water per second
... a cylinder with a 7 cm diameter and a 33 m length
... convert to mass of water
find energy (work) ... work = m g h
work / time = power ... Joules / sec = watts
