CalcTool: Gravity-fed pipe flow calculator

This calc is mainly for pipes full with water at ambient temperature and under turbulent flow. If you know the slope rather than the pipe length and drop, then enter "1" in "Length" and enter the slope in "Drop". If the cunduit is not a full circular pipe, but you know the hydraulic radius, then enter (Rh×4) in "Diameter".
