Find the kinematic and dynamic viscosity of air and water at

Find the kinematic and dynamic viscosity of air and water at 40 C and an absolute pressure of 170 kpa.

Solution

Dynamic viscosity of air at 170kpa and 40 C is = 19.201* 10^-6 Pa s

Kinematic viscosity of air = dyanamic viscosity/ density at that temperature and pressure

= 10.132 * 10^-6 m²/s

( density of air at 40 C and 170 kpa = 1.895 kg/m³ )

Values are verified from property of air tables at same temperature and pressure
