The solution to a generalized version of the classical calorimeter problem approximates the behavior of certain continuous exchange processes between particulate solids and a fluid. For modeling purposes, the much simpler energy-balance solution has obvious advantages, although it only holds for negligible intraparticle resistance and thus predicts too short contact times. An error diagram provides a quantitative comparison between those two results as a function of the two pertinent system parameters.
