An evaporative cooling system is necessary for power plants in water short areas. the cooling tower evaporates 3 percent of the inflow water and scaling (mineral precipitation) problems are avoided if the total dissolved solids (tds) is kept at or below 2000 g/m3 everywhere. salts are removed from the plant as blowdown liquid. makeup water has a tds of 1000 g/m3. (a) for a heated water flow rate of 10 m3/s, what makeup water flow rate and blowdown flow rate are needed for steady state operation? (b) to reduce the amount of new water required, a reverse osmosis unit is purchased that produces water with a tds of 100 g/m3 for re-use and concentrates the salts in a brine with a tds of 8000 g/m3. what makeup water supply flow rate, flow rate into the ro unit, and brine flow rate result when the ro unit is put into operation?
