Manning’s N-Value for Design Tests consistently show a Manning’s n in the range of 0.009 to 0.011. The major investigation (2005 Utah State University) recognized an effective Manning’s n as low as 0.0100. Manning’s n for design is conservatively factored to 0
30/5/2013· Just enter the diameter of pipe, depth of water, Manning''s n, constant (1.49 for English or 1 for Metric), and slope of energy line to calculate the flow rate. It will only take seconds. If you need to find the slope, just use the SOLVE function.
