Chlorine mass balance
Convert an independently specified active chlorine dose to mass flow.
Equation and assumptions
ṁCl₂ [kg/h] = Q [m³/h] × dose [mg/L] / 1000
Arithmetic mass flow only. Does not prescribe a dose or verify disinfection, residual, demand, contact time, pH, by-products or safe handling. It is not a drinking-water safety assessment.
