When analysing size distributions, why does the volume-weighted distribution generally differ from the number-weighted distribution for the same population?
Remember the story about the butcher selling lark and horse pâté?
When sampling particles in three dimensions, to which physical property is the probability of selection proportional if isotropic linear probes are used?
Consider the relationship between the size of the probe and the size of the feature on the object that it is likely to encounter.
What geometric condition is essential for using the point-sampled intercept (PSI) method to estimate vV?
This method is based on measuring lines whose orientation must be representative of all possible directions.
In what way does the ‘nucleator’ method differ technically from the PSI method during the measurement stage?
Note the difference between the variables l0 and ln in the volume estimation formulae.
Which formula can be used to estimate the coefficient of variation of particle volume (CVn(V)) from estimates of the volume-weighted and number-weighted mean volumes?
