Hello all
I was reading the topic "Hydraulic Radius of Partially Filled Circular Conduits" started by ankur2061 on May 20 2009. The spreadsheet he developed helps to calculate the hydraulic radius which is fine but I would like to know how to determine how full the pipe is? Is there any equation?
There is one more thing which I would like to check with you guys, the unit of average velocity calculated using the Manning equation is m/s however, I don't see a time factor anywhere. Is 'n' - manning's coefficient dimensionless or does it have a unit?
Thanks
Allen
