First of all I m giving a lot of thanks by heart to you to disclose the technology which was secret of sugar consultant. They are having this online calculation of capacity calculation but they never share it with others. You are realy thankful in this regards.

Can I ask to provide this method of calculation as a app for mobile . So that we can take calculation any time and save in our mobile.

Yours

Dear Sir,
My self Sivaramakrishna Alluri and working as a Deputy manager process. I am not a consultant.
Thank you very much for your valuable comment on my website. My intention is every technologist should know about basic concepts of each equipment in sugar industry.
In this connection I started this website. Now I have been working on this site whenever free time available.
I don’t have knowledge regarding app development.
However here I have given links for all calculators in one page for easy operation without any disturbance
