Worked Example
Verified calculation
Given:
- Inlet temperature = 77.3
- Inlet pressure = 2000000
- Outlet pressure = 101325
- Joule-Thomson coefficient = 2.45E-6
Expected Result:
- Outlet temperature = 72.64824625
Engineering Interpretation:
Under the given input conditions, the calculated result is: Outlet temperature = 72.64824625 K.
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
