Allowable Leakage in Pipes

?

Formula

Allowable leakage during the maintenance stage of pipe carefully laid and well tested during construction is given by:

qL=N*D*sqrt p/115

Where,

qL = Allowable Leakage in Cu.cm per hour,

N = Number of Joints in length

D = Diameter of pipe in mm,

P = Average Test Pressure during leakage Test in Kg/sq.cm.
