CESE Problem 137

[Carlito]

Hi,

Having problems with this one:

1) Looking at the solution, why is the value of L runout = 150’ and not 450’? (since 150’ is only L/3, i.e. the L runoff in the curve! – this info is given in the problem statement in the table and also in the solution to problem 135).

2) Why is T runout = 300’, and not 2L as in problem statement, i.e. why isn't it 2*450’ (L=450' from problem 135) = 900’?

Can any one help, please?

Cheers.

I think somebody posted about this same problem here long ago.Can't find it but I'm sure it is there.

No, cannot find any prior responses nor figure out the reasoning behind the solution... :-(
