Flow With LossesSource: Journal of Engineering for Gas Turbines and Power:;1965:;volume( 087 ):;issue: 001::page 37DOI: 10.1115/1.3678137Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Even when one is willing to estimate the various loss coefficients in a given system, it is not always an easy matter to determine the flow rate and/or the total pressure drop across the system. Heretofore, a tedious trial-and-error approach (at the least) has been indicated, and this has often been based on a Darcy approximation which is questionable under certain conditions. In this paper we present, for compressible and constant-density flows with losses, the developments of exact, albeit simplified, numerical and graphical solutions which are free from all iterative procedures. Comparisons are drawn between these exact analytical solutions and several Darcy approximations. Sample problems are given to illustrate the graphical and tabular solutions as presented here.
