Question

A jet of water impacts a flat plane oriented at an angle as shown. The flow is in the horizontal xy plane. The cross-sectional area of the jet is 1.7 in2 and the velocity is 16 ft/s. The angle θ is 67°.

Assume negligible friction. This assumption lets you (1) use the Bernoulli equation to determine v2 and v3, and (2) determine the direction of the force apriori (no friction means no shear along the surface of the plate):

(a) Determine the force exerted by the jet on the plate. Specify magnitude and direction. Be sure to be clear about the direction.

(b) Determine the flowrate (gpm) of each of the two resulting jets along the plate.
