Result Interpretation

Pump Rotordynamic Critical Speed Margin Checker Calculator computes Critical Speed Margin in rpm using the defined engineering formula and the input values provided.

Worked Example

Verified calculation

Given:

  • Design Safety Factor = 1.2
  • First Critical Speed = 3600
  • Rated Operating Speed = 2950

Expected Result:

  • Critical Speed Margin = 780

Engineering Interpretation:

Under the given input conditions, the calculated result is: Critical Speed Margin = 780 rpm.

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.
