WebThe volume of fluid passing by a given location through an area during a period of time is called flow rate Q, or more precisely, volume flow rate. In symbols, this is written as. Q = d V d t. 14.13. where V is the volume and t is the elapsed time. In Figure 14.26, the volume of the cylinder is Ax, so the flow rate is. WebThus, for a circular pipe or duct exhibiting laminar flow, the parabolic velocity profile is: The maximum velocity is observed at r=0, i.e., the center of the axis: The volumetric flow rate in the pipe is: Thus, the average velocity of the flow is: With rearrangement, we can get Poiseuille’s equation for pressure drop calculation as:
