Hi guys, I am still learning this software. 
I am trying to use trial and error to find the solution of depth (Y) in open channels using mathcad solver block. I have set all guess values and
constraints, how best can i solve this?
Or is there another way of determining the value of Y.
I have also attached the original question with step by step calculations and correct answers, in case one needs
to restart everything.
I appreciate your input and comments.
Thank you in advance.
