Question: In this system, d = 15 cm, D = 35 cm, and the head loss from the venturi meter to the end of the pipe

In this system, d = 15 cm, D = 35 cm, and the head loss from the venturi meter to the end of the pipe is given by h_L = 1.5 V ²/2g, where V is the velocity in the pipe. Neglecting all other head losses, determine what head H will first initiate cavitation if the atmospheric pressure is 100 kPa absolute. What will be the discharge at incipient cavitation? Assume α = 1.0 at all locations.
