To Complete this assignment you must. . .
1. Read through the following documents.
a. Review of RTD and Characterizing Mxing
b. Mixing Efficiency Determinations for Continuous Flow Systems
2. Prepare a spreadsheet that accepts tracer washout data.
3. In the spreadsheet process the tracer washout data so that it constructs the following two plots:
a) C (conductivity) against time
b) Ln(C/C0) against time
4. Use Excel's linear regression functions (not a trend line) to calculate the fraction of flow short-circuiting (n) and the mixed volume fraction (m). S. Notes for the Tracer Washout Test
a) The measured depth of water in the open channel reactor was 5 cm.
b) The surface area of the open channel reactor is 4 030 cm.
c) The flow rate of the inflow to the open channel reactor was measured as 87 mL in 23.7 seconds.
d) The mass of KCI (potassium chloride) added to the open channel reactor was 20.17 g.
e) The conductivity of the water in the open channel reactor before and after the addition of the KCI can be obtained from the recorded video (The video was recorded in a F4V format, and converted to MP4 and MOV formats: both run in Windows Media. These files are too large to upload to a server for downloading - obtain the video from me or watch it here.
f) The question regarding whether the relationship of conductivity to KCI concentration was linear can be demonstrated by analyzing the data presented in Table 4 of NISI Special Publication 260-142, 2004 Edition.
g) The units of conductivity in the video begin in itS/cm, change to mS/cm, and then return to μS/cm.
6. In the same spreadsheet above, on a separate worksheet, analyze the data in Table 4 to demonstrate the relationship between KCI conductivity and concentration.
