Water moves through a constricted pipe in steady, ideal flow. At the lower point shown in the figure below, the pressure is P1 = 1.70  104 Pa, and the pipe diameter is 4.0 cm. At another point y = 0.30 m higher, the pressure is P2 = 1.25  104 Pa and the pipe diameter is 2.00 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.
