To calculate the kinematic viscosity of a fluid, we need to know the dynamic viscosity and the specific gravity of the fluid.
Given data:
Dynamic viscosity (μ) = 0.5 poise
Specific gravity (SG) = 0.4
We will use the following formula to calculate the kinematic viscosity (ν):
ν = μ / SG
Let's substitute the given values into the formula:
ν = 0.5 poise / 0.4
Simplifying this expression:
ν = 1.25 poise
Therefore, the kinematic viscosity of the fluid is 1.25 stokes.
Explanation:
- The kinematic viscosity of a fluid is a measure of its resistance to flow under the influence of gravity. It is defined as the ratio of the dynamic viscosity to the specific gravity of the fluid.
- Dynamic viscosity is a measure of the internal friction of a fluid and is usually given in units of poise. It represents the resistance of the fluid to shear or flow.
- Specific gravity is the ratio of the density of a substance to the density of a reference substance (usually water). It is a dimensionless quantity and indicates the relative density of the fluid.
- In this question, the dynamic viscosity of the fluid is given as 0.5 poise and the specific gravity is given as 0.4.
- By dividing the dynamic viscosity by the specific gravity, we can calculate the kinematic viscosity.
- Substituting the given values into the formula, we find that the kinematic viscosity is 1.25 stokes.
- The answer is option 'C', 1.25.
