|
|
In a firefighting drill, a trainee learns to operate a fire hose. How much force should the trainee apply to hold the hose in a steady position? A nozzle is attached to the end of the hose to increase the velocity of the water. The nozzle outlet has a diameter of 3 in and the hose diameter is 6 in. The gage pressure at section 1 is 0.75 psi, and the water flows at a rate of 0.5 slugs/s. The length of the pipe is 2 ft. |
