Flow rate with viscosity

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. WebLaminar, Transitional and Turbulent Flow - Heat transfer, pressure and head loss in a fluid varies with laminar, transitional or turbulent flow. Liquids - Dynamic Viscosities - Absolute (dynamic) viscosity values for some common fluids. Liquids - Kinematic Viscosities - Kinematic viscosities of some common liquids like motor oil, diesel fuel ...
