My friend decided to be Mr. Macho and was welding without safety goggles. Now his eyes are burning pretty bad and he even has a runny nose. whats the best thing to do?
In this problem,the watt or kwatt is a problem of time to do the job,what you need to know is the speed of your pump. VR(omega),then Height(-)(1/2)10T^2 + V0T. GOOD LUCK.
To add to Lee Wang Tui's answer, you need to know the diameter of the hose approaching the nozzle and determine the velocity of the water before it gets to the nozzle, because the formula uses the change in velocity and the incoming velocity can't be zero. This information wasn't provided, so you can't calculate a truly accurate answer.
