Gpm and tdh
WebQ x TDH x Sp. Gr. 3960 bhp = Q x TDH x Sp. Gr. 3960 x Pump Efficiency The constant 3960 is obtained by dividing the number or foot pounds for one horsepower (33,000) by the weight of one gallon of water (8.33 pounds.) The brake horsepower or input to a pump is greater than the hydraulic horsepower or output due to the mechanical and hydraulic WebIn this example, our flow rate range comes out to 20.8-43 GPM.

WebMay 1, 2002 · The Chillers were recently replaced and new circulating pumps were added. The circulating pumps have a rating each of 375 GPM and TDH of 110 Ft. The return water has only a 6-7 F rise from the supply temperature. I understand there is a rule of thumb of 3 GPM per Ton of cooling and that Trane has used 2 GPM per Ton of cooling.
WebSep 29, 2012 · For example, many pumps with 3-inch discharges can produce flows of more than 700 gallons per minute (gpm), and 4-inch models can exceed 1,100 gpm. In fact, almost all pump sizes are capable of flows that exhibit extremely high discharge velocities. When this occurs, velocity head becomes an important component when measuring … WebRequired Flow Rate (GPM) Total Dynamic Head (TDH) As an example in the above curve, consider an NDP-40 Series pump performance curve with rubber diaphragms, pumping 80 GPM at 50-ft TDH.
