Worked Example
Verified calculation
Given:
- Number of Lactating Cows = 80
- CO₂ Production per Cow = 0.35
- Target Indoor CO₂ Concentration = 0.00114
- Ambient Outdoor CO₂ Concentration = 0.0004
Expected Result:
- Minimum Winter Ventilation Rate = 37837.837837838
Engineering Interpretation:
Under the given input conditions, the calculated result is: Minimum Winter Ventilation Rate = 37837.837837838 m³/h.
The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from automatically validated test cases.
