Liquid Flow Formulae

Air Flow Formulae

Q=Cv x Sq Rt (DP/d) or DP=d(Q/Cv)2

Where DP less than P1/2

Where DP equal to P1/2

Q=1.69Kv x Sq Rt (DPxP2)

Q = 0.84Kv x P1

Q = Flow L/Min

DP = Pressure Drop (Bar)

d = density i.e. Water = 1

Cv = flow factor coefficient of valve (L/Min)

(N.B. DP 5 - 10% is preferred)

Q = Flow (M3 Hr)
DP = Pressure Drop (Bar)
Kv = flow factor coefficient of valve (M3 Hr)
P1 = inlet pressure + 1 bar
P² = absolute downstream pressure =
(inlet pressure + 1 bar - DP)

PRESSURE

 1 Bar = 14.5 PSI

1 Bar = 100 kPa (Kilopascal)

1 PSI = 6.9 kPa

1 Kg/cm² = 0.98 Bar

1 Atmosphere = 1.013 Bar

1 Inch Water gauge = 2.49 mbar

1 mm Mercury = 1.33 mbar

1 Ton / in² = 154 Bar
 

 Volume

 1 Gallon (UK) = 4.54 Litres

1 Gallon (USA) = 3.79 Litres

1 Pint (UK) = 0.57 Litres

1 Pint (USA) = 0.47 Litres

1 Fluid Once (UK) = 28.4 cm³

1 Fluid Once (USA) = 29.6 cm³
 

FLOW

1 CFM = 0.472 Litres a second

1 CFM = 0.000472 m³/Sec

1 CFM = 28.32 Litres a minute
 

 Temperature

 From °F to C°

Add 40 then multiply by 5

then divide by 9 then -40

 From C° to F°

Multiply by 9 then –40
divide by 5 then +40
 

  Length

1 Inch = 25.4mm

1/16” Inch = 1.5875mm

1 foot = 0.305 Meters
1 Mile = 1.609 Kilometre
