Problem 3) a 70 ft long, 0.5 in diameter hose with a roughness of 0.0009 ft is fastened to a water faucet where the pressure is p1, determine p1 if there is no nozzle attached and the average velocity in the hose is 6 ft/s neglect minor losses and elevation changes. repeat the problem if there is a 0.25 in diameter nozzle attached to the end of the hose.

Plss anybody know how to do this? ? i need the answers from a through d
