At given SAR, infiltration rate increases as water salinity increases. Chlorine weighs 5 times more than Nitrogen (70/14), hence a perfect ratio is 5:1. Also, keep in mind that the volume of powders can vary from manufacturer to manufacturer. The formula is as follows:FC = HOCl + OCl-. The final product is Trichloramine which exits the pool as a gas. The breakpoint curve is a graphical representation of chemical relationship that exists with constant addition of chlorine to swimming pool water containing a small amount of ammonia-nitrogen. The differential equations presented in Table 8 were solved using the fourth order Runge-Kutta-Fehlberg algorithm. Chemically speaking, free chlorine is Chlorine (Cl2), Hypochlorous (HOCl) acid and Hypochlorite (OCl)- ion, which exist in the pool water, once it is chlorinated.
