Flow acceleration

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. WebThe term ò 8 ò P⁄ is called the local acceleration and vanishes if the flow is steady. The three terms in the parentheses are called the convective acceleration and rises when the particles move through regions of spatially varying velocity, e.g. nozzle.
