Question

An engine pumps water continuously through a hole. The speed with which water passes through the hole nozzle is v, and k is the mass per unit length of the water jet as it leaves the nozzle. Find the rate at which kinetic energy is being imparted to the water.

Open in App

Solution

Considering volume of water flown is $1$ sec,
$K E = \frac{1}{2} {m V}^{2}$
$= \frac{1}{2} (K V) V^{2}$
$= \frac{1}{2} K V^{3}$
