Dear Sudir,
Your impression that all here are experts in the field to identify the reason for your questions and the application of the same without revealing by the same by you is not correct. As this is for some evaluation of the process, why can't you delegate the issue to somebody in your organization who know the field.
Assume somebody like you will reply your questions and you follow the same for the evaluation!!!!!!!!!!

Dear Tushar,
Your suggestion is very right.
But in present work scenario one has to think on various fields of
engineering.
As a engineer one can understand any engineering issue, with the help of
friends like all of you who are already expert in this field.
Dear All,
By the way i am not using my design for any project. This is just for evaluation of the process. No body is going to get affected by my design.
All of Your responses are highly appreciated.
But as I dont have access to any of the books mentioned by you, i request all of you to send me the formulas either in writing or scanned.
As i have mentioned I tried Fanning's formula & Waymouth formula, but the
results of both are quite diverse.
So any of you is doing the same job i request to guide me.
Regards
Sudhir
