WebDynamic viscosity is a measure of the viscous forces and is a function of gas composition and static temperature. As viscosity has only a second-order effect on an engine cycle, … WebFrom dimensional analysis I find that the dynamic viscosity of an ideal gas must depend on its pressure p, density ρ and mean molecular free path l in this way: μ = C ρ p l.
