Which equation is used to calculate MFD?a.Peterman equationsb.Allen Cahn equationsc.Boltzmann’s equationsd.Maxwell’s equations

To determine which equation is used to calculate MFD (Mean Free Path Distribution), we must analyze the options provided:

1. Peterman equations: More commonly associated with spectroscopy and certain kinetic processes, not directly with MFD.
2. Allen-Cahn equations: These are primarily used in phase field modeling and do not pertain to the calculation of MFD.
3. Boltzmann’s equations: These are statistical equations used to describe the dynamics of a particle system and are relevant in the context of MFD, particularly for gases.
4. Maxwell’s equations: These govern the behavior of electromagnetic fields and are not related to the calculation of MFD.

Conclusion

The most relevant equation for calculating the Mean Free Path Distribution is Boltzmann’s equations. Thus, the correct answer is c. Boltzmann’s equations.
