For wide-range calculations, Perry’s uses empirical correlation equations. μ=μ0(0
Viscosity—the measure of a fluid's resistance to flow—is critical for sizing pumps, pipes, and heat exchangers. Perry's provides three main ways to find this data:
Thousands of organic and inorganic compounds are listed with experimental viscosity values at specific temperatures.
Liquid viscosity drops sharply as temperature rises. Perry’s often utilizes a variation of the :
