Program this formula into Excel to find the diameter at 50%–70% of the flooding velocity. Equation: 4. Calculating Packing Height scrubber design calculation excel hot

For an industrial "hot" scrubber design calculation in Excel, you need to structure your spreadsheet to handle gas cooling (quenching) mass transfer simultaneously | Parameter | Input | Formula | Result

Excel: Calculate NTU using logarithmic mean concentration difference (LMTD) for the pollutants. C. Output/Results Section Tower Diameter (meters) Total Packed Height (meters) Required Water Flow Rate (m³/h) Pressure Drop (Pa or in. WC) 3. Key Considerations for Hot Gas Applications Key Considerations for Hot Gas Applications Pressure drop

Pressure drop is the primary driver for operating cost (fan energy). Your Excel sheet should calculate ΔP using two separate methods depending on the scrubber type:
