A new solution for steady parallel flow in a rectangular duct is given that is valid for any aspect ratio ab where a and b are orthogonal half-widths of the duct, in contrast to older formulas that are restricted to certain ranges of ab. New solutions for oscillatory flow in rectangular ducts are also given that replace a set of invalid published solutions. They provide calibration constants for relating local and average values of the unsteady velocity flow measurements in any rectangular channel.
