The shower below is used to elect 3 1 gallons per minute for 46 = in I of water. Determine the pressure required at the bottom of the pips, Assume the total length of pipe is 10 1, and that the velocity out of the showerhead (different than that of the pipe) is 12 (1/s. Account for the three 90 degree bends (K, = 0.9 each) and the fully opened valve (K) - 0.25). Finally, take - -0.002.
