Flow rate q va
WebJan 24, 2024 · Flow rate Q is defined as the volume V flowing past a point in time t, or Q = \(\frac{dV}{dt}\) where V is volume and t is time. The SI unit of flow rate is m 3 /s, but … WebQ= dV dt Q = d V d t. where V is the volume and t is the elapsed time. In (Figure), the volume of the cylinder is Ax, so the flow rate is. Q= dV dt = d dt (Ax)= Adx dt =Av. Q = d V d t = d d t ( A x) = A d x d t = A v. Figure …
