Water moves through a constricted pipe in steady, ideal flow. At the lower point the pressure is 1.75 105 Pa and the pipe radius is 2.60 cm. At another point 2.50 m higher, the pressure is 1.28 105 Pa and the pipe radius is 1.60 cm.
(a) Find the speed of flow in the lower section. m/s
(b) Find the speed of flow in the upper section. m/s
(c) Find the volume flow rate through the pipe. m3/s
