where \(h_f\) is the head loss, \(f\) is the friction factor, \(L\) is the length of the coffee bed, \(D\) is the diameter of the coffee particles, \(v\) is the velocity of the water flow, and \(g\) is the acceleration due to gravity.

The heat transfer process can be described by the following equation: The Physics Of Filter Coffee Pdf

where \(J\) is the mass flux, \(D\) is the diffusivity, \(dc\) is the concentration gradient, and \(dx\) is the distance over which the diffusion occurs. where \(h_f\) is the head loss, \(f\) is
