Oil with a density of 890 kg/m3 moves through a constricted pipe in steady, ideal flow. At the lower point shown in the figure below, the pressure is P, = 1.95 x 104 Pa, and the pipe diameter is 8.00 cm. At another point y = 0.20 m higher, the pressure is P, = 1.15 x 10ª Pa and the pipe diameter is 4.00 cm.

Oil with a density of 890 kg/m³ moves through a constricted pipe in steady, ideal flow. At the lower point shown in the figure below, the pressure is P, = 1.95 × 104 Pa, and the pipe
diameter is 8.00 cm. At another point y = 0.20 m higher, the pressure is P, = 1.15 × 104 Pa and the pipe diameter is 4.00 cm.
(a) Find the speed of flow (in m/s) in the lower section.
m/s
(b) Find the speed of flow (in m/s) in the upper section.
m/s
(c) Find the volume flow rate (in m³/s) through the pipe.
