Momentum Diffusivity without Mass Diffusion in Liquids
I have been reading about the differences between momentum and mass diffusivity. I understand that mass diffusion occurs because of the "random walk" of individual molecules which over time ...

How to determine the slope for the gravity flow of highly viscous fluids (eg. gum)?
I am looking for a method to determine the slope of the pipe required to maintain a gravity flow for highly viscous fluid.
The Hazen-Williams equation for gravity flow is applicable for liquids which ...

Why is the kinematic viscosity unit m²/s when you only measure the time it passes a certain distance through a capillary rheometer?
Why did the scientists who designed the kin.viscosity measurement using a capillary rheometer setup decide to express the results in m2/s when all you measure is the time: the less viscous (faster ...

How to raise viscosity of water
I need to measure a machine for a liquid of which I know the viscosity (89 Kinetic Viscosity) but I don't have the liquid at hand. Is there a clever way of increasing viscosity of water to 89?

Is the net viscous work done at a stationary wall equal to zero?
From the following site:
Ref:https://www.me.psu.edu/cimbala/learning/fluid/CV_Energy/home.htm
I read that the the net work done by viscous force at a stationary wall is zero.
I understand that the ...
