Penstock thickness
Webrecommends a minimum thickness in mm equivalent to 2.5 times the diameter in metres plus 1.2 mm. Other organisations recommend as minimum thickness tmin= (D+508)/400, where all dimensions are in mm. The wall thickness required depends on the pipe material, its ultimate tensile strength (and yield), the pipe diameter and the operating pressure. WebBased on the comparison, the optimum diameter of the penstock is 0,45 meters with a thickness of 0,0018 meters which is calculated using the formula from Moffat, as well as a generation power of ...
