Bifurcation Ratio (Rb) = ΣN / ΣN + 1

ΣN = Total number of stream of a particular order.

ΣN + 1 = Total number of stream of a next higher order.

How do you calculate the bifurcation ratio?

You add the number of streams that branch off the main stream which is the first order then you add the number of streams branching off that stream whih becomes the 2nd order and the sum of the no. of stream orders divided by the number of streams gives the bifurcation ratio.

How do you calculate difurcation ratio?

There is no such thing as "difurcation". Please check the spelling, and ask another question, clarifying whether you mean "bifurcation", "difraction", or perhaps something entirely different.

What is damping ratio in control system?

Damping ratio in a control system is a measure of how fast the system returns to equilibrium after being disturbed. It indicates the system's ability to dissipate energy and reduce oscillations. A higher damping ratio results in a faster and smoother response with less overshoot.


What is the significance of bifurcation ratio?

The bifurcation ration is the relationship between the number of steams of one order an those of the next highest order. It is calculated by dividing the number of streams in one order by the number in the next order. For example , in a basin :N1/N2 = (number of the first order streams / number of second order streams) = 20/4 = 5N2/N3 = (number of the second order streams / number of third order streams) = 4/2 = 2N3/N4 = (number of the third order streams / number of fourth order streams) = 2/1 = 2then, by finding the mean of each rations in the basin being studied :(5 + 2 + 2)/3 = 3 = bifurcation ration for this basin.*** the significance of this ratio is that as the ration is reduced so the risk of flooding within the basin increases. it also indicates the flood risk for parts of the basin.

How do you calculate velocity ratio in a pulley?

To calculate the velocity ratio in a pulley system, divide the diameter of the driving pulley by the diameter of the driven pulley. This ratio indicates how much faster or slower the driven pulley rotates compared to the driving pulley. It helps to determine the speed or force transmission in the pulley system.
