A Power-Law Formulation of Laminar Flow in Short Pipes

In the quantification of air flow through penetrations in buildings, it is necessary to be able to characterize the flow without detailed knowledge of the geometry of the paths. At the conditions typical of buildings, the flow regime is partially developed laminar flow. This report develops a theoreticfal description of the hydrodynamic relationship based an a power-law representation between the air flow and applied pressure for laminar flow in short pipes
