Özet

This paper presents general equations for pressure drop calculations for developed and developing laminar flow in ducts of arbitrary cross sections. The results obtained from these equations compare well with the theoretically calculated values available in the literature for circular, rectangular, triangular, elliptical, polygonal, casped, corner and side ducts. The maximum deviations by these comparisons are 7.3 and -4.0 percent, respectively. Besides these, the equations yield satisfactory results for eccentric and concentric annular ducts.
