This eliminates the need for calibration tests to characterize the coefficients. Without such a model, the uncertainty of the flow coefficients is dramatically increased and expensive calibration may be required.
Empirical test data from independent laboratories verified the theoretical model and flow coefficients as a constant, independent of Reynolds number and within ±0.5% of the predicted value.
The derivation of the theoretical model and test data is published in the Verabar Flow Test Report (VED-100).
