For the water flow between two reservoirs in Figure 5, the flow rate is found to be 0.016 m/s. What is the head loss in the pipe in meters? If atmospheric pressure is 100kPa and the vapor pressure is 8kPa, for what constriction diameter D in centimeters will cavitation occur? Assume no additional losses due to changes in the constriction. 25 m 10 m 5 cm Figure 5
