The image above represents the basin length.To calculate basin length, seven essential parameters are needed and these parameters are Unit Inflow Rate (Qn), Advance Time (Tt), Manning’s Co-efficient (n), Inflow Rate (Q), Parameter (a), Parameter (b) and Parameter (l).
The formula for calculating basin length:
L = 6E4QnTt / [aTtb/(l + b)] + (1798n3/8Qn3/8Tt3/16)
Where:
L = Basin Length
Qn = Unit Inflow Rate
Tt = Advance Time
n = Manning’s Co-efficient
Q = Inflow Rate
a = Parameter
b = Parameter
l = Parameter
Let’s solve an example;
Find the basin length when the unit inflow rate is 2, the advance time is 3, the manning’s co-efficient is 4, the inflow rate is 6, parameter is 8, the parameter is 10 and the parameter is 5.
This implies that;
Qn = Unit Inflow Rate = 2
Tt = Advance Time = 3
n = Manning’s Co-efficient = 4
Q = Inflow Rate = 6
a = Parameter = 8
b = Parameter = 10
And then l = Parameter = 5
L = 6E4QnTt / [aTtb/(l + b)] + (1798n3/8Qn3/8Tt3/16)
L =Â 6E4(2)(3)Â /Â [(8)(3)(10)/(5 + 10)] + (1798(4)3/8Â . (2)9/16Â . (3)3/16)
That is, L = 360000Â /Â [240/15] + (1798(1.68) . (2.739) . (1.228))
L =Â 360000Â /Â [16] + (3023.86 (2.739)(1.228))
L =Â 360000Â /Â 16 + 10179.64
So, L = 360000Â /Â 10195.64
L = 35.30
Therefore, the basin length is 35.30.
