Calculates CSTR steady-state conversion from space time τ and rate law, solving the design equation: X = τ × (−r_A) / C_A₀. For first-order kinetics: X = kτ/(1+kτ) — a CSTR with Damköhler number kτ = 9 achieves 90% conversion.
Inputs
Tau Min
Duration of the process. Make sure units match the rate inputs (seconds, minutes, or hours).
K Per Min
Amount per unit of time or per unit quantity. Check the denominator before interpreting.
Cin Mol L
Amount of solute per unit volume. Higher concentration = more solute dissolved.
