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:
lnμ=A+BT+ClnT+DTEl n mu equals cap A plus the fraction with numerator cap B and denominator cap T end-fraction plus cap C l n cap T plus cap D cap T to the cap E-th power Perry's Handbook Viscosity
If you've spent any time in a chemical engineering lab or plant, you’ve likely encountered . Often called "the ChE Bible," its Section 2 is the go-to for physical property data, specifically viscosity . Why Engineers Use Perry’s for Viscosity Viscosity—the measure of a fluid's resistance to flow—is
Liquid viscosity drops sharply as temperature rises. Perry’s often utilizes a variation of the : Why Engineers Use Perry’s for Viscosity Liquid viscosity
is in Kelvin. For many common hydrocarbons, simpler forms like are provided.
Thousands of organic and inorganic compounds are listed with experimental viscosity values at specific temperatures.
