Best Answer

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.

What is the Calculation of bifurcation ratio of third order stream?

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 a 1 in 40 fall mean on drainage pipe?

It generally refers to a ratio of the 'fall' in drainage from the insert or 'inlet' to the 'outlet' calculated byusing fall = ratio X distance 1:40 would be 1/40 = 0.025 - assume a 3 meter distance for eg sake. fall = 0.025 X 3 fall = 0.075 or 75mm from the inlet to the outlet.

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.


What is the deviation ratio for frequency modulation?

Deviation ratio: In a frequency modulation system, the ratio of the maximum frequency deviation of the carrier to the maximum modulating frequency of the system under specified conditions
