Example 2.23: Calculate the viscosity of liquid nitrogen at 300 °K. Use ξ = 0.0407, ω = 0.047

Solution

$ Reduced temperature, T_r = 0.793.

$ Viscosity group for liquid (η_Lξ)^(o) (Table 2.1) = 0.00296

$ Viscosity group for liquid (η_Lξ)⁽¹⁾ (Table 2.1) = 0.00307

$ Viscosity group (η_Lξ) (Equation 2.67)

$

$

$ Viscosity, η_L (Equation 2.67)
