What is the effect of the P43® on tank internals such as heating coils, roof drains and water drawoff lines?
Care should be taken in the installation of the P43® to ensure that the centre line of the jet does nto directly impact tank internals in the vicinity of the P43®, as this would reduce the penetration of the jet. For purposes of doing a detailed structural analysis on the impact of the jet on tank internals, the following equation may be used to determine the centre-line velocity of the jet at any distance from the P43®: U = 0.1776 x Q/KD Where U = Jet Centre Line Velocity (Ft/Sec) Q = Flow per Nozzle (USGPM) X = Distance from Nozzle (Feet) D = Nozzle Diameter (Inches) Based upon our operating experience to date, no damage has occurred to roof drains or water drawoff lines resulting from the P43®. Tank internals should be secured from drifting off supports, in most cases this has already been done with U-Bolts.
