If the RQ is 6 and the k2t is 4, what is the removal efficiency of (CO2) of the co-current tower aerator. What will be the efficiency if a tower aeration with counter current flow is used instead?

what is the efficiency of the co-current tower aerator (%):

what is the efficiency of the counter current tower aerator (%):

To calculate the removal efficiency of carbon dioxide (CO2) in an aerator, we need to use the formula:

Removal Efficiency (%) = (1 - (Cout / Cin)) * 100

Where:
- Cout is the concentration of CO2 in the outlet stream
- Cin is the concentration of CO2 in the inlet stream

For the co-current tower aerator:
Given that RQ (Removal Quotient) is 6 and k2t is 4, we can determine the concentrations of CO2 in the outlet and inlet streams. However, more information is needed to determine the specific values for Cout and Cin. Could you provide the values for Cout and Cin?

Once the values for Cout and Cin are known, you can substitute them into the removal efficiency formula to calculate the efficiency of the co-current tower aerator.

Similarly, for the counter current tower aerator:
Again, we need the values for Cout and Cin to calculate the efficiency of the counter current tower aerator using the same removal efficiency formula.

Please provide the specific values for Cout and Cin for both co-current and counter current tower aerators, and I will be able to calculate the efficiency for each.
