Water (density `rho`) is flowing through the uniform tube of cross-sectional area A with a constant speed v as shown in the figure. Find the magnitude of force exerted by the water on the curved corner of the tube is (neglect viscous forces)
A. `sqrt(3) rho A v^(2)`
B. `rho Av^(2)`
C. `sqrt(2) rho Av^(2)`
D. `(rho Av^(2))/(sqrt(2))`
