Chemical dosing
Convert a specified process dose into mass and stock solution flow.
Equation and assumptions
ṁ = Q × C / 1000 [kg/h]; Qstock = Q × C / Cstock [L/h]
Steady flow; concentration refers to active chemical. Does not select a safe or effective dose, account for reactions, or size a dosing system.
