9. Pump: Head, Pressure, and Power. Water ( = 1.94 slug 3;=2.34105 psf.s) is pumped through a horizontal, 0.5 -ft-diameter pipe (0.01 relative roughness) and discharges into the atmosphere with a velocity of 12ft/s. At a distance of 500ft upstream from the end of the pipe a pressure gage reads 0 psi. A pump and a valve (loss coefficient KL=10 ) are located between the pressure gage and the end of the pipe. What are the head, pressure, and power added by the pump? [1hp=550ftbf/s;g=32.2ft/s2.] Ans. 107ft;46.5psi;28.7hp
