P. = 1.90 x 104 Pa, and the pipe diamneter is 7.0 cm. At another point y = 0.40 m higher, the pressure is P,
= 1.30 x 104
Pa and the pipe diameter is 3.50 cm.
Po
(a) Find the speed of flow in the lower section.
m/s
(b) Find the speed of flow in the upper section.
m/s
(c) Find the volume flow rate through the pipe.
