Question

A liquid of density $\rho$ is coming out of a hose pipe of radius a with horizontal speed v and hits a mesh. 50% of the liquid passes through the mesh unaffected. 25% looses all of its momentum and 25% comes back with the same speed. The resultant pressure on the mesh will be

Select the correct option:

A

$\frac{3}{4} \rho v^2$

B

$\frac{1}{4} \rho v^2$

C

$\frac{1}{2} \rho v^2$

D

$\rho v^2$
