If a pump speed is selected (1,200, 1,800 or 3,600) for a pump, then the pump curve graph will show multiple pump curves at various impeller diameters.Dec 17, 2011 · BHP = (3.9 x 450 x 1.73 x 0.85) / 1000 = 2.6 hp. This is slightly less than the expected 3.2-hp, meaning a straight horizontal line at 2.6-hp intersects the power curve at flow approximately 50-gpm, depending how accurately you eyeball the curve. Obviously, too many assumptions and approximations in reading curves bring bad news. In the case of a positive displacement pump, increasing the pipe length causes the fluid pressure at the pump end of the pipe to go up at a constant flow rate, until the pressure limit of the pump is hit. Increasing the pipe length beyond that point will cause the flow rate to fall because the pump is now behaving like a constant-pressure pump.There are a lot of recommendations around on what the flow rate through water heating solar collectors should be. I'm aware of these: - Heliodyne recommends a range of 0.025 gpm/sf to 0.075 gpm/sf. - SunEarth recommends 0.025 gpm/sf for their collectors. - Solar discussion groups often talk about 0.02 to 0.03 gpm/sf a good number.Using a timer, open the valve nearest the pump location until the bucket is full. Use the pump flowrate calculation: Divide the container volume by the length of time it took to fill up to get the flow rate. 5 gallons / 1 minute = 5 gallons per minute. 5 gallons /30 seconds (0.5 minutes) = 10 gallons per minute.The volume flow rate formula can be written in symbols as: Q =. V T. where V denotes volume and t denotes time. The SI unit for the flow rate is m/s, although there are many other units for Q in general use.
