Dynamic viscosity is a measure of a fluid's resistance to flow under shear stress, while kinematic viscosity is a measure of a fluid's resistance to flow under gravitational forces. Dynamic viscosity is expressed in units like Pascal-seconds (Paยทs) or centipoise (cP), while kinematic viscosity is expressed in units like square meters per second (m^2/s) or centistokes (cSt). The two are related through the fluid's density, with kinematic viscosity being the ratio of dynamic viscosity to density.

What is the kinematic viscosity of water at sixty degrees Fahrenheit?

The kinematic viscosity of water at 60 degrees Fahrenheit is approximately 1.40 centistokes.


What is the kinematic viscosity of water?

The kinematic viscosity of a fluid is found by dividing the dynamic viscosity by the density of the fluid. The kinematic viscosity of water changes depending on the temperature of the water. It ranges from .29 SI units to 1.787 SI units.


What is this : The property of fluids that resist to flow?

This is viscosity, which is a measure of a fluid's resistance to deformation and flow. It is influenced by factors such as temperature, pressure, and the composition of the fluid. Viscosity is classified as either dynamic (absolute) viscosity or kinematic viscosity.


What is Difference between kinematic and dynamic quantity?

Kinematic quantities describe motion without considering the forces causing it, such as speed and acceleration. Dynamic quantities, on the other hand, involve forces and their effects on motion, such as force, momentum, and energy. Essentially, kinematic quantities focus on describing motion, while dynamic quantities involve the forces that cause that motion.


Does density tie in with viscosity?

Density and viscosity are related but not the same. Density is a measure of how tightly packed the molecules in a substance are, while viscosity is a measure of the resistance of a fluid to flow. Generally, substances with higher density tend to have higher viscosity, but there are exceptions based on the molecular structure of the substance.

Does temperature directly proportional or inversely proportional to the kinetic and dynamic viscosity?

Temperature is inversely proportional to the dynamic viscosity, which is the measure of a fluid's resistance to flow. As temperature increases, the dynamic viscosity of a fluid typically decreases. However, for some fluids, the kinetic viscosity, which is dynamic viscosity divided by the fluid density, can increase with temperature due to changes in the fluid's density.
