# What is kinematic viscosity of air?

## What is kinematic viscosity of air?

The viscosity of air depends mostly on the temperature. At 15 °C, the viscosity of air is 1.81 × 10-5 kg/(m·s) , 18.1 μPa·s or 1.81 × 10-5 Pa·s . The kinematic viscosity of air at 15 °C is 1.48 × 10-5 m2 /s or 14.8 cSt. At 25 °C, the viscosity is 18.6 μPa·s and the kinematic viscosity 15.7 cSt.

What is kinematic viscosity formula?

The units of kinematic viscosity are established on time and area. It is the ratio of the dynamic viscosity to its density, a force independent quantity. It is the ratio of the area of time; henceforth it is m22/s or ft22/s. The kinematic viscosity formula is expressed as, ν = μ/ρ

What is the viscosity of air at 20 ℃?

Kinematic viscosity of air at 20°C is given to be 1.6 × 10-5 m2/s.

What is the SI unit of viscosity * 2 points?

pascal second
The SI unit of viscosity is the pascal second (Pa·s) or kg·m−1·s−1. The SI unit of kinematic viscosity is square meter per second or m2/s.

What is the viscosity of air at STP?

1) The dynamic viscosity of air at STP is 17.89 Mu N s/m^2 (that is micro Ns/m^2) Calculate the corresponding value in Poise (P), and lbf s/ft^2.

## What are the types of viscosity?

There are two types of viscosity: dynamic viscosity, measured in pascal seconds, and kinematic viscosity, measured in metres per second squared. Viscosity is used as a way to predict when volcanoes erupt.

What are the dimensions of viscosity?

The dimensions of viscosity can be determined based on how it is defined. It is defined as the property of a fluid that describe a stress (force/area) per velocity shear rate in the fluid (d velocity/d distance). So the dimensions are (F/A)/(V/L). That can be rearranged to F/(At) = F/(L^2 t). That could be changed to (m L/t^2)/(L^2 t) = m/(Lt).
