Suppose a pump moves 500 gallons of water per minute (GPM) against a total head of 100 feet. Find the WHP.Plugging the values into the equation:WHP = 500 x 100 / 3960WHP = 50000 / 3960WHP = 12.63The water horsepower in this scenario is approximately 12.63....
and is usually expressed by the formula Hydraulic power Ph = Flow rate X Total developed head X Density X Gravitational constant Pump Efficiency is the ratio of pump input and output power. i.e Efficiency of the pump is the ratio water horse power to break horse power. Pump Efficiency = ...
The Formula for PSI: Feet of Head/2.31 = PSI Flow is the volume of water a pump can move at a given pressure. Flow is indicated on the horizontal axis in units like gallons per minute, or gallons per hour, as shown in Figure 2.Fig. 2. A basic pump performance curve for ...
The total head developed by the pump, the power required to drive it, and the resulting efficiency vary with the capacity. When a pump manufacturer develops a new pump the pump is tested for performance under controlled conditions. The results are plotted in the form of graphs that show flow...
When you leave the General page during initial installation of the pump (with the Demo Mode being disabled), Chromeleon attempts to connect to the pump, retrieve the settings from the pump firmware, and set the options (pump type and pump head) on the corresponding wizard pages. Confirm the...
The heads in subsequent stages are additive so a pump with a given number of stages develops a total head calculated as the product of the total number of stages and the head per stage. This rule allows one to find the number of stages required to develop the total head to overcome the...
That is why they are using head instead of pressure. The following formula converts pressure to the head; H(meter) = 10.2 P/SG or H(feet)= 2.3P/SGOnce the rated flowrate has been determined, the designer subsequently specifies the total head (H) needed at this flowrate. ...
= q(m3/hr)x ρ(kg/m3)x g(m2/s)x h(m)x p(Pa)/ 3600000. The same way pump power in horsepower formula can be written as, Pump Power P(HP)= q(m3/hr)x ρ(kg/m3)x g(m2/s)x h(m)x p(Pa)/ 2685600. Also above pump power is required to lift the liquid to head ...
Total pond gallons Total dynamic head pressure Width of spillway on waterfall (if you will have a waterfall) Fish load Voltage / Energy Consumption Total pond gallonscan be figured out by using the following formula: Rectangular or Square Pond: ...
