Recirc.Rate
FORMULAS
Approximately 0.85% of Recirc. Rate is Evaporated per 10 F (5.6 C) Delta T Evaporation = RR * dT * EC Blowdown Flow Rate = Evaporation / (CR-1)
Make-Up Flow Rate = Evaporation + Blowdown Tower Calcium = Make-Up Calcium * CR HTI = 0.0116 * (Gallons Capacity/ gpm BD) (metric) =0.693*System Capacity/BD Rate Acid Feed = (MU Alk.- (Target Alk./CR))*MU Flow
