DARCY-WEISBACH VS DIÂMETRO: EQUAÇÃO DE PERDA DE CARGA

The Darcy-Weisbach equation is one of the first to appear in any fluid mechanics course, but most plant engineers have never stopped to look at how the diameter enters the calculation. It appears twice, in the velocity squared and in the denominator of the equation, and the combined effect puts the diameter practically in the fourth power of the head loss. In this postgraduate Fluid Handling Engineering class, we show the equation, identify the kinetic energy term V²/2g, simulate in the Engineering & Co. app how a 5 mm difference in piping takes the pump from 3 hp to 8 hp, and indicate why the factor f is the only unknown variable in an existing installation. 📲 DOWNLOAD THE ENGINEERING AND CO.
