A water jet leaves a fixed nozzle with a velocity of 10 m/s.
The jet diameter is 10 cm. A 30o
cone is pushed into the water
jet at a speed of 5 m/s. The water impinges on the cone with the
jet axis and the cone axis in perfect alignment so that the water
is divided evenly by the cone. Bernoulli’s equation suggests that
because the pressure on the jet boundary is constant, the water
velocity relative to the cone surface is constant. Determine the
thickness of the water stream when it reaches the base of the
cone.
