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.
Difference between dynamic and kinematic viscosity?
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 (Pa·s) 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.
How can one determine the dynamic viscosity of a fluid?
The dynamic viscosity of a fluid can be determined by measuring the resistance of the fluid to flow. This is typically done using a viscometer, which measures the rate at which the fluid flows through a tube of known dimensions under a specified pressure or force. The viscosity is then calculated using the formula for dynamic viscosity, which relates the flow rate, pressure, and dimensions of the tube.
What is the viscosity cSt of 2 diesel fuel -20 deg F?
The viscosity of No. 2 diesel fuel at -20°F is typically around 4.0-6.0 cSt (centistokes). However, it's important to note that the exact viscosity can vary depending on the specific blend and composition of the diesel fuel.
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 Kinematic viscosity?
It is the ratio of the dynamic viscosity to the density of the fluid.

What is the engeneering unit of viscosity?
You have to distinguish dynamic viscosity and kinematic viscosity. Different units are used for both - the standard (SI) unit for dynamic viscosity is Pascal x second, while the unit for kinematic viscosity is meter2/second.
Si unit of coefficient of viscosity?
The Si unit for viscosity is Pa·s = kg/(s·m).
What is the viscosity cP of 2 diesel fuel?
The viscosity of Diesel 2 at 37.8 degrees Centigrade is 2 to 6 centistokes. This is equivalent to 32.6 to 45.5 SSU.

How do you find absolute viscosity of fluid?
Measuring the viscosity of the liquid with different types of viscosimeters.The more correct word is dynamic viscosity.

Is kerosene more viscosity than diesel?
viscous, and yes, it is a thicker liquidthan diesel
What is the viscosity of distilled water at 25 degrees centigrade?
The dynamic viscosity of glycerin at 25oC is: 0.9934 kg/m∙s = 9.934 poise
Do liquid and gases have high dynamic viscosity?
No, liquids and gases typically have lower dynamic viscosity compared to solids. Dynamic viscosity is a measure of a fluid's resistance to deformation under shear stress, and both liquids and gases have lower resistance compared to solids due to their molecular structure and higher mobility of particles.
