1. (10 pts, 5pts, 5pts) Water flows through a circular nozzle, exits into the air as a jet, and strikes
a plate. The force required to hold the plate steady is 140 N. Assuming frictionless onedimensional flow, estimate
(a) The velocities (V1 and V2) at section (1) and (2);

(1)
(2)

Answer:

Given that:
F = 140N
D1 = 10cm
D2 = 3cm
Steady flow, incompressible, friction is negligible.
