Water at T = 25°C is drawn from an underground detention tank and discharged into a drain using a 6-m-long pipe and pump. The pipe has a diameter of 100 mm and a friction factor of f = 0.02. Determine if cavitation occurs when the velocity through the pipe is 4 m/s and h = 4 m. Use the pump performance curves in Fig. 14–16. The atmospheric pressure is 101.3 kPa. Neglect minor losses.
