So, dynamic viscosity may be defined as the tangential force per unit area necessary to move a fluid in one horizontal plane relative to another plane at a velocity of unit value while the fluid’s molecules remain a unit distance …

WebMay 7, 2024 · The dynamic viscosity coefficient divided by the density is called the kinematic viscosity and given the Greek symbol nu. nu = mu / r Re = V * L / nu The units of nu are length^2/sec. Here's a Java program to calculate the coefficient of viscosity and the Reynolds number for different altitude, length, and speed. WebThe lower a liquid’s viscosity, the slower the rotor turns and the higher the speed difference between tube and rotor: Low-viscosity forces transfer only a small part of the preset tube speed to the rotor. Mathematically put, dynamic viscosity is inversely proportional to the speed difference between tube (n 2) and rotor (n 1).
