The height of fluid on capillary action by surface tension

Posted on September 25, 2020

Today, we will get the height of fluid on capillary action by surface tension. Usually we know the maximum height formula but not generalized formula. So we will derive the generalized formular by Newtonian mechanics and Lagrangian mechanics. [Read More]

Fluid Dynamics

The method of measuring viscosity

Posted on September 15, 2020

Our fluid dynamics professor, Lee, gave us the homework about how the viscosity is measured by conical viscometer. This is not that difficult problem if you know how to derive the surface area of rotating body and most importantly, the due date of this homework is right after tomorrow so... [Read More]
