= = 6.) Water enters a pump at Pg = 0 and flows up a vertical pipe (z = L = 25 m; D = 4 cm, /D = 0.005) at Re = 3 x 105. The flow then exits the pipe at Pg 0. Neglecting minor losses: (a.) what pump power input is required? (b.) What is the gauge pressure Pg at the pump outlet? (c.) repeat parts a and b for the pump power and pump exit Pg, if the flow had been assumed incorrectly) to be laminar. 25m Pg=0 Pum
