Water at T = 25°C is drawn from an underground detention tank and discharged into a drain using a 9-m-long pipe and pump (Figure 1). The pipe has a diameter of 100 mm and a friction factor of f = 0.02. The atmospheric pressure is 101.3 kPa. The velocity through the pipe is 4 m/s and h = 2 m. Neglect minor losses.
