![Example (1-1): Find the force exerted by a 5 cm diameter water jet
directed against a flat plate held normal to the exit of stream. The
velocity of the jet is 35 m/s.
Example (1-2): A 2.5 cm diameter water jet exerts a force of 90 kN in
the direction of flow on a flat plate which is held inclined at an angle
of 30° with the axis of stream. Find the rate of flow.](https://content.bartleby.com/qna-images/question/aa171a4d-5fc1-4888-8384-0a97f5991be3/098420b7-a631-4bae-9e3a-d1740574276b/9e8wav8_thumbnail.jpeg)
