The coupling is modelled using an empirical relationship between the excess potassium ion concentration in the extracellular space following SD and the vessel radius.
WebA A is the cross sectional area of a section of the pipe, and v v is the speed of the fluid in that section. So, we get a new formula for the volume flow rate Q=Av Q = Av that is often more useful than the original definition of volume flow rate because the area A A is easy … WebFlow rate and velocity are related by Q = A¯v Q = A v ¯ where A A is the cross-sectional area of the flow and ¯v v ¯ is its average velocity. For incompressible fluids, flow rate at various points is constant. That is, Q1 = Q2 A1¯v1 = A2¯v2 n1A1¯v1 = n2A2¯v2.
