A liquid of density 
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:
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
Mass per unit time = 3Av
Force due to momentum loss = 
Force due to bounce back = 
Pressure =
