16.2.5 Pressure in a flowing system
s.g.
P = (Hs- Hf) x
2.31
where P = Gauge pressure in pounds per square inch
Hs = Static Head of liquid in feet
Hf = Friction Head in feet
s.g. = Specific Gravity of the liquid being pumped
16.2.6 The Effect of capacity change on pipe friction
[ Q~212] 2 = Hf 1Hf2
where Q = Flow Rate
Hf = Friction Loss
16.2.7 The effect of head change on the flow rate
-- .s,
where Q = Flow Rate
Hs = Static Head
16.2.8 The effect of changes in pipe diameter on the friction in a
system
where D = Pipe Diameter
Hf = Friction Loss
