Water moves through a constricted pipe in steady, ideal flow. At the lower point the pressure is 1.68 105 Pa and the pipe radius is 2.90 cm. At another point 2.50 m higher, the pressure is 1.25 105 Pa and the pipe radius is 1.30 cm.
(a) Find the speed of flow in the lower section.
(b) Find the speed of flow in the upper section.
(c) Find the volume flow rate through the pipe.
