Worked Example

Verified calculation

Given:

  • 10th Percentile Residence Time = 12.5
  • 50th Percentile Residence Time (Median) = 25
  • 90th Percentile Residence Time = 48.2
  • Mean Hydraulic Residence Time = 28.9
  • Standard Deviation of Residence Times = 11.7

Expected Result:

  • RTD Skewness Magnitude Deviation = 0.56584497420205

Engineering Interpretation:

Under the given input conditions, the calculated result is: RTD Skewness Magnitude Deviation = 0.56584497420205 dimensionless.

The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from deterministically validated test cases.

Formula / Method

rtd skewness magnitude deviation = abs((pow(90th percentile residence time - mean hydraulic residence time, 3) + pow(10th percentile residence time - mean hydraulic residence time, 3) + pow(Median - mean hydraulic residence time, 3)) / (3 * pow(standard deviation of residence times, 3)))
