11. Estimation of the Mass Transfer Coefficients
The chapter discusses the estimation of mass transfer coefficients in various systems using empirical correlations derived from experimental data. It emphasizes the importance of understanding the mass transfer process and the factors influencing these coefficients such as geometry, velocity, and diffusion properties of different chemicals. Techniques for measuring mass transfer coefficients through controlled experiments are also highlighted, along with the application of these coefficients in real-world scenarios.

Key Concepts
- -- Mass Transfer Coefficient
- A measure of the rate at which a substance is transferred from one phase to another.
- -- Empirical Correlations
- Equations derived from experimental data that relate mass transfer coefficients to various influencing factors.
- -- Flux
- The rate of flow of a property per unit area, often used to describe the transfer of mass.
- -- Diffusion Coefficient
- A measure of how easily particles spread from areas of high concentration to low concentration.
