How do you find the kinematic viscosity of air?
1 Kinematic Viscosity (ν) The kinematic viscosity is an atmospheric variable defined as the ratio between the dynamic viscosity μ and the density ρ of the fluid, i.e. and depends on both air temperature and pressure. For air at sea level pressure and 20 °C, ρ = 1.205 × 10−3 g cm−3 and ν = 0.15 cm2 s−1.
How do you calculate kinematic viscosity from dynamic viscosity?
The formula for the conversion is:
- Kinematic (cSt) x Density = Dynamic (cP)
- Dynamic (cP) / Density = Kinematic (cSt)
What is the dynamic viscosity of air at 20c?
Kinematic viscosity of air at 20°C is given to be 1.6 × 10-5 m2/s.
What is the kinematic viscosity of air at 20 degrees Celsius?

How do you calculate the kinematic viscosity of a fluid Mcq?
Explanation: ν = μ/ρ, where ν = kinematic viscosity, μ = dynamic viscosity and ρ = density of the fluid. 11. The kinematic viscosity of a fluid is 0.1 Stokes.
How do you find kinematic viscosity from specific gravity?
Calculation: Given: Specific gravity = 1.9, Kinematic viscosity = 6 stokes ⇒ 6 × 10-4 m2/s. ∴ ρ = 1.9 × 1000 = 1900 kg/m3.
What is ETA in viscosity?
The dynamic viscosity η (η = “eta”) is a measure of the viscosity of a fluid (fluid: liquid, flowing substance). The higher the viscosity, the thicker (less liquid) the fluid; the lower the viscosity, the thinner (more liquid) it is. SI unit of dynamic viscosity: [η] = Pascal-second (Pa*s) = N*s/m² = kg/m*s.
How is ETA viscosity calculated?
The more usual form of this relationship, called Newton’s equation , states that the resulting shear of a fluid is directly proportional to the force applied and inversely proportional to its viscosity. The similarity to Newton’s second law of motion (F = ma) should be apparent….(dynamic) viscosity.
