QUESTION 3 (25 Marks) Water flows from one reservoir
A
to another reservoir
B
through a pipe of variable diameter as shown in the figure below. Pipe AC is
40m
long and
100mm
in diameter while pipe
CB
is
60m
long and
150mm
in a diameter. Darcy's friction
f
for both pipes equals 0.006 . The gradual expansion at
C
is at an angle of
10\deg
. The pipe entrance at
A
and exit are sharp. Considering all losses, 3.1 Determine the flow rate from reservoir
A
to
B
at the instant when the difference in elevation is
20m
.(20) 3.2 Plot the total energy line and the hydraulic grade line for the pipeline ACB at the ṣame instance, indicating values/levels at all salient points. (10)
