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 7.0 cm. At another point y = 0.20 m higher, the pressure is P2 = 1.15 104 Pa and the pipe diameter is 3.50 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.
