Question

A hose pipe used for grinding is ejecting water horizontally at the rate of 0.5 metre per second area of Bore of the pipe is 10 cm square calculate the force applied by grinder to hold a pipe horizontally stationary

Answer 1

Explanation:

density of water= 1000 kg/m^3

force exerted by jet of water on pipe

= 1000*10*10^-4*0.5^2

= 0.25 N
