Worked Example

Verified calculation

Given:

  • Maximum specific growth rate = 0.25
  • Oxygen half-saturation constant = 0.002
  • Desired specific growth rate = 0.2

Expected Result:

  • Critical oxygen concentration = 0.01

Engineering Interpretation:

Under the given input conditions, the calculated result is: Critical oxygen concentration = 0.01 mol/m^3.

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

critical oxygen concentration = maximum specific growth rate * oxygen half-saturation constant / (maximum specific growth rate - desired specific growth rate)
