Power law rules - OK?

The object of this article is to compare the performance of these two flow representations against a small set of measurement data using the concepts outlined in the Air Infiltration and Ventilation Centre's Calculation Techniques Guide.2 A particular aspect of the approach presented is that in each case an identical solution technique, flow network and pressure field has been applied, thus enabling a direct comparison of each of the flow representations to be made. The tests were by no means exhaustive and further evaluation is recommended.
