What it calculates
The “Capillary Number” calculator computes Ca (Capillary) from 3 parameters: µ, pa·s, v, m/s, σ, n/m.
A standard physics formula used in educational and engineering tasks.
Example calculation
With parameters µ, Pa·s = 0.001, v, m/s = 0.01, σ, N/m = 0.072 the result is 0.0001 (Ca = μv/σ).
