There are two types of viscosities of a fluid. One is called dynamic or absolute viscosity or simply VISCOSITY. The other is called kinematic viscosity.

When a fluid moves, a shear stress develops in it and its the magnitude depends on the viscosity of the fluid. Shear stress, can be defined as the force required to slide one-unit area layer of a substance (here this substance is a fluid) over another. Therefore, shear stress is a force divided by an area and can be measured in the units of N/m² (Pa) or lb/ft². In fluids such as water, oil, or other common liquids the magnitude of the shear stress is directly proportional to the change of velocity between different positions in the fluid and such a change of velocity is also called as shear rate. The constant of proportionality is called the dynamic viscosity of the fluid. The term absolute viscosity is also used for dynamic viscosity.

Application areas of units of viscosity:

1.    Viscosity of oil:

• Application: Determining the viscosity of an oil at a specified temperature in terms of square meters per second (m²/s).
• Unit: m²/s

2. Falling-Ball Viscometer:

• Application: Measuring the viscosity of a heavy fuel oil using a falling-ball viscometer.
• Units: Viscosity in various units.

3. Capillary Tube Viscometer:

• Application: Measuring the viscosity of an oil using a capillary tube viscometer.
• Units: Viscosity in various units.

4. Oil Flow through a 45° Elbow:

• Application: Determining the horizontal force exerted by oil flowing through a horizontal 45° elbow.
• Units: Force in Newtons (N).

5. Viscosity of Water:

• Application: Obtaining the absolute and kinematic viscosity of water at various temperatures using given data.
• Units: (a) Absolute viscosity in lb-sec/ft², (b) Kinematic viscosity in ft²/sec.

6. Fluid with Absolute Viscosity and Specific Gravity:

• Application: Calculating velocity gradient and shear stress at various points in a fluid with specific viscosity and specific gravity.
• Units: Velocity gradient in reciprocal seconds (s⁻¹), shear stress in lb/ft².

7. Estimating Viscosity of Olive Oil:

• Application: Estimating the viscosity of olive oil at a given temperature.
• Units: Viscosity in centipoises (cP).

Note: The viscosity units in each case depend on the specific measurement technique or context. Some cases require additional calculations to determine viscosity in standard units (e.g., m²/s or lb-sec/ft²) based on provided data.
