Please solve it clearly.

T = Q/BxL.
BxL = 378/2 = 189,
Usually L = 4B,
Therefore 4B^2 = 189,
B = 6.87~ 7m.
BxL = 378/2 = 189,
Usually L = 4B,
Therefore 4B^2 = 189,
B = 6.87~ 7m.

@ALL.
Here, the units don't match.
LHS: In seconds.
RHS: In m/s.
How can you use it then?

Here T = Q/BxL.

I think Q=AV and V considered 2m/hr.

Q=378,
T=2hr,
Vol=QT=756m3.
Let depth D=4m.
Area B*L=Vol/D=189m2.
We know L=4B.
A=L*B=4B2=189m2.
So, B=6.87m~7m.
T=2hr,
Vol=QT=756m3.

@Naveen.
This is not a Formula.
You can compare the dimensions both sides, One side is sec. And other side is m/sec.

@Naveen.
V = Q/(B*L).
V= settling velocity.
V = Q/(B*L).
V= settling velocity.
