Does anyone know equations that can be used to equate fluid viscosity using the terminal velocity of a mass falling down a tube of that liquid?
Thanks

Try this equation for terminal velocity of a falling sphere of radius R:tntcoder said:Does anyone know equations that can be used to equate fluid viscosity using the terminal velocity of a mass falling down a tube of that liquid?
Fluid viscosity is a measure of a fluid's resistance to flow, or its "thickness." It is an important concept in fluid mechanics because it affects the behavior of fluids in various systems, such as in pipes and pumps.
One commonly used equation for calculating fluid viscosity is the Newtonian viscosity equation, which states that viscosity is equal to the product of dynamic viscosity (μ) and shear rate (γ). This equation is often used for simple fluids, such as water and air.
Yes, there are various other equations that can be used to calculate fluid viscosity, depending on the type of fluid and its behavior. Some examples include the Navier-Stokes equation, the Hagen-Poiseuille equation, and the Sutherland equation.
Temperature and pressure can both have significant effects on fluid viscosity. Generally, higher temperatures result in lower viscosity, while higher pressures result in higher viscosity. This is because temperature and pressure can affect the molecular structure and interactions of the fluid, altering its flow behavior.
Yes, fluid viscosity can be measured experimentally using various methods, such as viscometers and rheometers. These instruments measure the resistance to flow of a fluid under specific conditions and can be used to determine its viscosity. However, the accuracy of these measurements may vary depending on the type of fluid and the experimental setup.
