The Filter’s Role: The paper filter acts as a boundary layer. It provides resistance and captures insoluble lipids (oils) and fines. The "work" of the filter is to ensure that only the desired molecular weight compounds end up in the carafe. 3. Thermodynamics: The Energy of Extraction The Physics of Filter Coffee: A Comprehensive Guide
Chapter 3 — Heat Transfer and Temperature Control The "work" of the filter is to ensure
: These "fines" can migrate and clog the filter paper, a phenomenon known as pore-blocking 🌊 Fluid Dynamics & Flow Darcy’s Law The flow of water through the coffee bed follows Darcy’s Law , which relates flow rate to pressure and permeability. Permeability : Determined by grind size and distribution. Bed Height : A deeper bed increases resistance and contact time.
