Question
Transcribed Image Text:8.63 Two reservoir maintain a constant difference of
water levels of 11.25 m and are connected by
a 10 cm diameter pipeline of 294.3 m length.
The total of all head losses, by friction valve
losses, bend losses, inlet and exit losses, and
velocity head can be taken as 98.1 v²/2g (in m)
where v is the flow velocity through the pipe (in.
m/sec). Assuming that the valve at the
downstream end is suddenly opened so that
there is no pressure wave, what will be the time
taken for the velocity of flow in the pipe to attain
95% of the steady terminal velocity? Take
