At 15 ☌, the viscosity of air is 1.81 × 10-5 kg/(m The viscosity of air depends mostly on the temperature. What is dynamic and kinematic viscosity of air? Is viscosity dependent on pressure?īased exclusively on very general considerations concerning the relationship between viscosity and “free volume,” we show that, at moderate values of pressure, viscosity increases, as a rule, with increasing pressure, provided the liquid is in stable or metastable (undercooled) equilibrium states. Kinematic viscosity of air at 20☌ is given to be 1.6 × 10-5 m2/s. Water at 20.2oC (68.4oF) has the absolute viscosity of one – 1 – centiPoise….Dynamic (absolute) Viscosity. How do you find the dynamic viscosity of air?Įquation (1) is known as the Newtons Law of Friction. This problem has been solved: Solutions for Chapter 2Problem 146P: The dynamic viscosity of air at 20☌ and 200 kPa is 1.83 × 10–5 kg/m What is the dynamic viscosity of air at 20c?įluid Mechanics Fundamentals and Applications (3rd Edition) Edit edition. See kinematic viscosity, eddy viscosity, Newtonian friction law. While the dynamic viscosity of most gases increases with increasing temperature, that of most liquids, including water, decreases rapidly with increasing temperature. 10 How do you convert viscosity to density?įor dry air at 0☌, the dynamic viscosity is about 1.7 × 10-4 g cm-1s-1.8 What is dynamic viscosity and its units of measurement?.7 What is difference between dynamic and kinematic viscosity?.6 What is the formula for dynamic viscosity?.5 Does dynamic viscosity of air change with pressure?.3 What is the viscosity of air at 20 ℃?.2 What is the dynamic viscosity of air at 20c?.1 What is the dynamic viscosity of air?.
