a water pipe has a nozzle at its outlet. the velocity of the water stream emerging from the nozzle is 'v' and the area of cross-section of the nozzle is 'A'. if 'd' is the density of water ,find the force experienced by nozzle due to the emerging water stream

Solution

In a second:
volume that will come out is = vA
so mass that is coming out = dvA
momentum per second= force= dv²A
