The specific gravity of a liquid with a viscosity of 0.06 Poise and a kinematic viscosity of 0.025 Stokes

Introduction:
The specific gravity of a liquid is a measure of its density relative to that of water. It is an important property that helps in understanding the behavior and characteristics of the liquid. In this case, we are given the viscosity of the liquid in Poise and the kinematic viscosity in Stokes. We will use these values to determine the specific gravity of the liquid.

Understanding viscosity:
Viscosity is a measure of a fluid's resistance to flow. It determines how easily a fluid can be deformed or how it flows under an applied force. There are two types of viscosity: dynamic viscosity and kinematic viscosity.

- Dynamic viscosity: It is a measure of a fluid's internal resistance to shear or flow and is usually denoted by the symbol 'μ' (mu). It is measured in Poise or Pascal-seconds (Pa·s).
- Kinematic viscosity: It is the ratio of dynamic viscosity to the density of the fluid and is denoted by the symbol 'ν' (nu). It is measured in Stokes or square centimeters per second (cm²/s).

Calculating specific gravity:
The specific gravity of a liquid can be calculated using the following formula:

Specific gravity = Density of liquid / Density of water

In this case, we are not given the density of the liquid directly. However, we can use the relationship between density, viscosity, and kinematic viscosity to find the specific gravity.

Density = Dynamic viscosity / Kinematic viscosity

To find the density of the liquid, we need to convert the viscosity values given in the problem statement to consistent units.

Unit conversion:
- 1 Poise = 0.1 Pascal-second (Pa·s)
- 1 Stokes = 0.0001 square meter per second (m²/s)

Converting the given values:
- Viscosity = 0.06 Poise = 0.06 * 0.1 Pa·s = 0.006 Pa·s
- Kinematic viscosity = 0.025 Stokes = 0.025 * 0.0001 m²/s = 0.0000025 m²/s

Calculating density:
Density = Dynamic viscosity / Kinematic viscosity
Density = 0.006 Pa·s / 0.0000025 m²/s = 2400 kg/m³

Calculating specific gravity:
Specific gravity = Density of liquid / Density of water
Specific gravity = 2400 kg/m³ / 1000 kg/m³ (density of water) = 2.4

Conclusion:
The specific gravity of the liquid with a viscosity of 0.06 Poise and a kinematic viscosity of 0.025 Stokes is 2.4.
