UDC 532.57 : 681.121.853 : 532.542 WRD 1
Reaffirmed 2021

1 Scope

1.1 This standard lays down the procedures for estimation offlow in closed circular horizontal conduits flowing full and freelydischarging into atmosphere as a free jet. The characteristic ofthis free jet are expressed in terms of the vertical drop of thejet over a certain horizontal distance from the free end of thepipe.

1.2 This method should not be used where there is a heavytendency of jet to disintegrate and when the jet fluctuatesviolently.
