# .BuildingSystems.Airflow.Multizone.Points_m_flow

Powerlaw with flow coefficient and flow exponent fitted based on 2 datapoints

## Information

Model that fits the flow coefficient of the massflow version of the orifice equation based on 2 datapoints of mass flow rate and pressure difference.

A similar model is also used in the CONTAM software (Dols and Walton, 2015).
