WebAll the graphs are related by the equation “flow = speed * density”; this equation is the essential equation in traffic flow. The fundamental diagrams were derived by the plotting of field data points and giving these data points a best fit curve. With the fundamental diagrams researchers can explore the relationship between speed, flow ... WebThis equation applies to a steady, uniform, isentropic flow. There are several observations that can be made from an analysis of Eq. (9.26). They are: For a subsonic flow in an expanding conduit (M <1 and dA>0), the flow is decelerating (dV <0). For a subsonic flow in a converging conduit (M <1 and dA <0), the flow is accelerating (dV >0).
