Abstract
Paper presents new mathematical model for air flow velocity distribution in rounded rectangular
ducts and its experimental verification. In papers [1, 2] an mathematical model based on modified Prandtl
equation for power power-law velocity profile was determined. It works very well for smaller cross
sections. During the study of larger cross sections new phenomena in flowing air have been observed, it
forced the search for a new model. The new model is based on a rounded rectangular division into two
parts: slot and rounded square.
