This might explain why the model fails at low speeds. Very often in fluid mechanics, no analytical solutions are available since many dimensionless nuers are inextricably linked and very often, experimental data (obtained with calibrated sensors in flows of known speed) are used to determine the coefficients that relate these dimensionless nuers between them.
