 Pump vs Head GPH Calculator
Hi everyone,
I just found this and I thought some of you may be interested. Advanced Aquarist's Online Magazine - Feature Article: Pump Head Loss Calculator - Easing System Design
Its a calculator for GPH. It lets you input a number of variables.
The pump list is kind of old, but you can find a pump that matches your gph if you don't see yours.
Calculate with all 0 values to see what the pump's GPH is.
I found it while working on a custom mod for my liquid cooling system for my PC.
This program works on Windows, and I've found it works on Vista too. It says you can get it to work on Linux too, probably by using Wine. Haven't tried it on my fedora install yet.
