Flow rate,
Assume, turbulent flow.
∴ turbulent flow.
[ Step 2 ] Determine the maximum flow rate
[ Step 3 ] Determine the total friction loss, in the pipe & fittings
Pump outlet : point 1, overhead tank inlet : point 2 로 놓고 Bernoulli Eq.
linear velocity,
( assuming )
Average velocity =
Equivalent roughness, = 0.00015 ft ( from textbook p 482 )
∴ Friction factor = f = 0.0045 ( from Fig. 14-1 )
Total Le for fittings & valves
Le =
Friction due to flow through pipe & all fittings
∴
[ Step 4 ] EQ % valve sizing
From Valve Performance Eq.
∴
[ Step 5 ] Pump selection
Total Head at normal flow rate, from the pump performance chart,
Check :
So the recommended pump : 68.5% efficiency, 28HP , 8` pump
[ Step 6 ] Resizing of Pipe

A Glove vavle is used
At given conditions : water at 61℉
norm…(drop)
