I have to do the math the good 'ol fashioned way! ![]() |

![]() How accurate do you want to be? The math can get ugly. Friction coefficients of pipe, laminar vs. turbulent flow, pipe diameters, restrictions in fittings, etc

specific gravity is 1.025 for SW Go ahead and get ugly with me. I enjoy a challenge! I'd like to be within +/- 250 gph for accuracy, but I'm not going to lose sleep over a mistake. I just like to know what's going on with my system. What I want to do is install an orifice plate or turbine flowmeter but that would be a bit extreme ![]() |

![]() Sedra 20000
I can't find a comparable pump for 2000 gph at 0 head on reefcental's chart. Most of them are little pumps. The Iwakis are sort of comparable but I don't recognize the models that are on the list. Plus my Sedra's internal and the Iwakis are external, which kind of plays into the math a bit. |

![]() As per another site, time how long it takes to fill a 1 gallon jug, average out the times and convert gallons per second into gallons per hour.
