"WebSep 12, 2014 · Eta is the viscosity. So this is the viscosity of the fluid. And the volume flow rate's inversely proportional to the viscosity because the more viscous the fluid, the more it resists flowing, and the less meters cube you'll get per second. And it's inversely proportional also to the length of the tube. " - Flow rate with viscosity
