I have the volumetric flow rates of the incoming streams of different NaCl concentrations and mass concentrations of sodium chloride concentration. F1= 10000L/s C1=20.0mg/L F2= 5000L/s C2= 40mg/L how would I go about finding the volumetric flow rate of the mixture in a mechanically stirred tank an the NaCl concentration in the exiting stream at steady state? Thank you for any help you can give me.

For the concentration now. Both will mix to give some concentration C, in a volume V (which you got as the exiting flow rate). Concentration times volume gives you mass. And the rate on inflow of mass should be the same as the rate of outflow of mass. Hence, C1V1 + C2V2 = CV Divide by units of time, C1F1 + C2F2 = CF __________________ Jerry (Got my results!) It is easier to protect your feet with slippers than to cover the earth with carpet. No one can go back and change a bad beginning; but anyone can start now and create a successful ending. If a problem can be solved, no need to worry about it. If it cannot be solved what is the use of worrying?
