Chemical Engineering
Fenske Equation Calculator
Compute the minimum number of theoretical equilibrium stages required for a binary distillation separation using the Fenske equation. The "best case" stage count at total reflux — actual columns need more stages because they operate at finite reflux.
Fill in the required fields to see your result.
Chemical Engineering
Reynolds Number Calculator
Compute the Reynolds number Re = ρvD/μ — the dimensionless ratio of inertial to viscous forces in a flowing fluid. The single most important number for predicting laminar vs turbulent flow in pipes, channels, and around objects.
