A liquid of density ρ is coming out of a hose pipe of radius a with horizontal speed v and hits a mesh.<p></p>

The correct option is B
34pv2
Momentum per second carried by liquid per second is ρav2
net force due to reflected liquid = 2 × [14ρav2]
net force due to stopped liquid = 14ρav2
Total force = 34ρav2
net pressure = 34ρv2
