Organizing and summarizing search results for you- Scherrer formula: Dp = (0.94 Χ λ) / (β Χ Cosθ)
- Stokes’ law: used to calculate the size of particles that settle out of the fluid as a function of time, and a particle size distribution is generated by plotting the measured concentration of particles against the calculated particle diameter.
- Calculation of mean values: can be done using the tabulated data. Then multiply the individual values of each measurement class by the mean size measurement class and then sum them up.
- Particle Size Analyzers (PSA): devices based on different technologies, such as high definition image processing, analysis of Brownian motion, gravitational settling of the particle and light scattering (Rayleigh and Mie scattering) of the particles.
