Question

Water flows at 3m/s through a pipe of diameter0.1m and strikes a vertical plate near the outlet of the pipe. If the stream of water strikes the plate normally,calculate the force exerted in the plate( density of water is 1000kg/m

Answer 1

$$F=pA=(0.5\rho v^2)(0.25\pi d^2)$$

$$F=(0.5(1000)(3)^2)(0.25\pi (0.1)^2)=35\ N$$
