HEAD

A term used to define water pressure in vertical feet or meters.

Converting Head to Pressure


Converting head in feet to pressure in psi


Pump curves in feet of head can be converted to pressure
- psi - by the expression:

p = h SG / 2.31 (1)

where
p = pressure (psi)
h = head (ft)
SG = specific gravity


Converting pressure in psi to head in feet

h = p 2.31 / SG (3)

where
h = head (ft)
p = pressure (psi)
SG = specific gravity


Converting head in meter to pressure in bar


Pump curves in meter of head can be converted to pressure
- bar - by the expression:

p = h SG / 9.81 (2)

where
h = head (m)
p = pressure (bar)
SG = specific gravity


Converting pressure in bar to head in meter


h = p 9.81 / SG (4)

where
h = head (m)
p = pressure (bar)
SG = specific gravity


Example - Converting Pump Head - feet - to Pressure - psi.

The pressure - psi - of a water pump operating with head 120 ft can be expressed as:
p = (120 ft) 1 / 2.31
= 52 psi

Note: Higher Pressure rating pipes upto 800'/24kgf/cm2  and 1000ft/30kgf/cm2 are available on request.

The delivery pressure of the pump should never exceed the working pressure of the pipes connected to the pump at the bottom as under:

DEPTH CALCULATION OF BOREWELL AND PRESSURE RATINGS

Let:
d = Depth (feet)
pt = Pressure required at top (kgf/cm2)
ph = Head Loss (1kgf/cm2)
pp= Pipe pressure Rating (kgf/cm2)

Depth = [pp – (pt+ph) x 33']

For example:
If fusion medium pipe of 3'' is used and pressure required is 3/kgf/cm2 at top.
Hence

D = [15-(3+1) x 33']
     =  11 x 33= 363'

So pipe can be lowered up to 363 feet.

Note: Higher Pressure rating pipes upto 800'/24kgf/cm2  and 1000ft/30kgf/cm2 are available on request.
