Is the resistance loss in a pipe lower for turbulence compared to laminar flow? !
Thread Content
See the figure below (Moody diagram). The pipeline material has been determined, the pipe diameter has been determined, and the relative roughness has been determined. The lower the flow velocity, the lower the Re. As shown in the diagram, the further to the left the friction curve moves, the greater the coefficient of friction and the greater the resistance loss. The friction coefficient in this laminar region and transition region is much higher than that in the turbulent region. What’s going on? !
The calculation of frictional losses cannot rely solely on the coefficient of friction; you forgot about the kinetic energy term
