NEW EQUATION FOR FRICTION-FACTOR APPROXIMATION DEVELOPED

Brian F. Towler, Timothy L. Pope University of Wyoming Laramie A new equation for approximating the Moody friction factor in gas flow calculations includes gas viscosity and gives a better approximation for a wide range of Reynolds numbers than four existing, more widely known equations. All of these latter four discount effects of gas viscosity. Only the IGT equation (Institute of Gas Technology, Chicago) applies to a wide range of flow velocities (Reynolds number = Nre).
