The Book "Pumps as Turbines" gives a flow rate of 85.5 l/s for a 250mm pipe (about 12") and 138 l/s for 300mm. This produces a head loss of 1% per unit lenght...
Mike: This is our speciallity. You have to apply a rainfall-runoff model, but you should have measurements or records of some closest stream gage of your ...

Dave, I normally suggest a pipe sizing rule of thumb to keep the flow velocity in the range of 3-5 ft/sec or 1-1.5 m/sec. However with such a short pipe you...
Rob: Your data is quite incomplete, you are not saying what is power you are getting from the system you have built. Also, please define the water volume that...
