Worked Example

Verified calculation

Given:

  • Steam mass flow rate = 8.5
  • Inlet steam specific enthalpy = 3412
  • Outlet steam specific enthalpy = 2785.2
  • Injection water specific enthalpy = 417.46
  • Mixed stream water-specific enthalpy (saturated liquid at outlet pressure) = 418.5

Expected Result:

  • Water injection mass flow rate = 5122.8846153845

Engineering Interpretation:

Under the given input conditions, the calculated result is: Water injection mass flow rate = 5122.8846153845 kg/s.

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.
