Hausner Ratio Formula
The following formula is used to calculate the Hausner Ratio.
HR = \frac{TD}{BD}Variables:
- HR is the Hausner Ratio
- TD is the Tapped Density
- BD is the Bulk Density
To calculate the Hausner Ratio, divide the Tapped Density by the Bulk Density.
What is the Hausner Ratio?
The Hausner Ratio is a measure of the flowability of a powder or granular material. It is calculated as the ratio of the Tapped Density to the Bulk Density of the material. A higher Hausner Ratio indicates poorer flowability, while a lower ratio indicates better flowability. This ratio is commonly used in the pharmaceutical, chemical, and food industries to assess the handling and processing characteristics of powders.
How to Calculate Hausner Ratio?
The following steps outline how to calculate the Hausner Ratio.
- First, measure the Bulk Density (BD) of the material.
- Next, measure the Tapped Density (TD) of the material.
- Finally, calculate the Hausner Ratio using the formula HR = TD / BD.
- After inserting the values and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
Bulk Density (BD) = 0.5 g/cm³
Tapped Density (TD) = 0.65 g/cm³
