As shown in the figure, when a water stream of diameter D (m) hits a plate with a hole of diameter d (m) at speed V (m/s), and the water stream passes through the hole at v (m/s), Find the force F (N) on the plate.

F = ¥ñ*q*V = ¥ñ*A*V^2

A : area of water stream

F = ¥ñ*(¥ð/4)*D^2*V^2 - ¥ñ*(¥ð/4)*d^2*v^2

When d = (D/2), v =V,

F = ¥ñ*(¥ð/4)*D^2*V^2 - ¥ñ*(¥ð/4)*(1/4)*D^2*V^2

= (3/16)*¥ñ*¥ð*D^2*V^2

*** Âü°í¹®Çå[References] ***

F = ¥ñ*(¥ð/4)*D^2*V^2 - ¥ñ*(¥ð/4)*d^2*v^2
