Hydraulic Institute. (Figure 1)NPSHA is the net positive suction head available of the system to the pump, and it is calculated during design and construction or determined from the actual system. And a valid equation to determine the NPSHA is:Where:Pb = atmospheric pressure (barometric pressure)Pv = vapor pressure of the delivery fluidPi = pressure in the closed intake vesselPs = pressure at the suction branch? = density of the delivery fluidci = velocity of the fluid in the intake vesselcs =...

The business of finding solutions to difficult onsite wastewater challenges is right up R.C. Worst & Co.’s alley. For the past 9 years, R.C.
