Question

Water moves through a constricted pipe in steady,
ideal flow. At the lower point shown in the figure, the
pressure is P1 = 1.75x104
Pa and the pipe diameter is
6.00 cm. At another point y = 0.250 m higher, the
pressure is P2 = 1.20 x 104
Pa and the pipe diameter is
3.00 cm. Find the speed of flow (a) in the lower section
and (b) in the upper section.
(c) Find the volume flow rate through the pipe.
Ans. ( (a) 0.638 m/s (b) 2.55 m/s (c) 1.80 x 10-3 m3
/s ).

Water moves through a constricted pipe in steady,
ideal flow. At the lower point shown in the figure, the
pressure is P1 = 1.75x10' Pa and the pipe diameter is
6.00 cm. At another point y = 0.250 m higher, the
pressure is P2 = 1.20 x 10ª Pa and the pipe diameter is
3.00 cm. Find the speed of flow (a) in the lower section
and (b) in the upper section.
(c) Find the volume flow rate through the pipe.
