A water jet leaves a fixed nozzle with a velocity of 10 m/s. The jet diameter is 10 cm. A 30° 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. Bernoulliâs equation suggests that because the pressure on the jet boundary is constant, the water velocity relative to the cone surface is constant.

Required:
Determine the thickness of water stream when it reaches the base of the cone.
