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 = 0.40 m higher, the pressure is P2 = 1.25 104 Pa and the pipe diameter is 2.50 cm.
A) find the speed of flow in the lower section in m/s
B) find the speed of flow in the upper section in m/s
C) Find the volume flow rate through the pipe in m^3/s
