Water moves through a constricted pipe in steady, ideal ow. At the lower point shown in the figure below, the pressure is 1.85 x 105 Pa and the pipe radius is 2.70 cm. At the higher point located at y = 2.50 m, the pressure is 1.26 x 105 Pa and the pipe radius is 1.20 cm. P2 l P1 y (D (a) Find the speed of ow in the lower section. E m (b) Find the speed of flow in the upper section. E m (c) Find the volume ow rate through the pipe. E me. Need Help? *
