The coffee slurry is a porous medium. Water flows through interstitial spaces between particles. The flow rate is governed by :
For many, brewing a cup of filter coffee is a morning ritual. For physicists and chemists, it is a complex display of fluid dynamics, thermodynamics, and mass transfer. Understanding the physics of filter coffee doesn't just satisfy curiosity—it allows you to engineer a better-tasting cup. The Physics Of Filter Coffee Pdf
Plugging in numbers: [ T_final = \frac(200 \times 4.18 \times 96) + (15 \times 1.2 \times 22)(200 \times 4.18) + (15 \times 1.2) \approx 92.5°C ] The coffee slurry is a porous medium
