Water moves through a constricted pipe in steady, ideal flow. At the lower point shown in the figure below, the pressure is P1 = 2.00 104 Pa, and the pipe diameter is 5.0 cm. At another point y = 0.30 m higher, the pressure is P2 = 1.00 104 Pa and the pipe diameter is 2.50 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
