What is Viscosity of fluid?

Viscosity is a measure of a fluid's resistance to flow. It determines how easily a fluid can be deformed or how smoothly it can move within itself. In simple terms, it is the internal friction within a fluid that opposes its motion.

Factors that influence viscosity include temperature, pressure, and the presence of dissolved solids or gases in the fluid. As temperature increases, the viscosity of most fluids tends to decrease.

What is the significance of Viscosity Correction Factor?

Viscosity correction factors are used to account for the changes in fluid viscosity due to variations in temperature. The viscosity of fluids typically decreases as temperature increases. When calculating the performance of a heat exchanger, it's important to consider the impact of changing viscosity on heat transfer and pressure drop. The viscosity correction factor is a mathematical adjustment used to incorporate the effects of varying viscosity into heat exchanger calculations.
