Question

The viscosity of SAE 10W30 oil is μ=0.100 N s/m2. Determine its kinematic viscosity. The specific gravity is So=0.92. Express the answer in SI and FPS units.

Answer 1

`\\u =0.000108\ (m^2)/(sec)`

`\\u =0.001161\ (ft^2)/(sec)`

Step-by-step explanation:

Given that

`\mu =0.1\ Pa-s`

Specific gravity of fluid S=0.92

So that density of fluid

`\rho=920\ (kg)/(m^3)`

As we know that ,kinematic viscosity of fluid is given as

`\\u =(\mu )/(\rho)`

Now by putting the values

`\\u =(0.1 )/(920)`

`\\u =0.000108\ (m^2)/(sec)`

So the kinematic viscosity of fluid in SI

`\\u =0.000108\ (m^2)/(sec)`

The kinematic viscosity of fluid in SI

`\\u =0.001161\ (ft^2)/(sec)`
