Question

A hose pipe used for gardening is
ejecting water horizontally at the rate of 0.5 m/s.
Area of the bore of the pipe is 10 cm . Calculate
the force to be applied by the gardener to hold
the pipe horizontally stationary.​

Answer 1

Explanation:

velocity v = 0.5 m/s

force required by gardener to hold the pipe = force exerted by the jet of water

= density of water * area of pipe*v^2

= 1000*0.1*0.5^2 = 25 N
