Siphonic Roof Drainage System Calculation

Hello,

I currently have completed the conventional roof drainage calculation with the attached for your reference.

Basically, I will need to have the same features as per the conventional roof drainage such as Roof Area, Elevational Area, Rainfall Intensity & Number of roof outlet to calculate the total flow rate in l/s for siphonic roof drainage system.

Only bid if you are completely confident to be able to complete the project. No time waster please!
