Irrigation Engineering When a canal flowing under pressure is carried below a natural drainage such that its F.S.L. does not touch the underside of the supporting structure, the structure so provided, is called Syphon Super passage Aqueduct Syphon-aqueduct Syphon Super passage Aqueduct Syphon-aqueduct ANSWER DOWNLOAD EXAMIANS APP
Irrigation Engineering The uplift pressure on the face of a drainage gallery in a dam is taken as None of these two-third of hydrostatic pressure at toe plus one-third of hydrostatic pressure at heel average of hydrostatic pressure at toe and heel hydrostatic pressure at toe None of these two-third of hydrostatic pressure at toe plus one-third of hydrostatic pressure at heel average of hydrostatic pressure at toe and heel hydrostatic pressure at toe ANSWER DOWNLOAD EXAMIANS APP
Irrigation Engineering If the height of the hydraulic gradient line above the floor of thickness t is h and the specific gravity of the material of the floor is G, the minimum thickness t of the floor downstream of the crest-wall, is given by the equation t = (h + 1)/(G + t) t = (h + 1)/G t = (h - 1)/(G + t) t = (h - 1)/(G - t) t = (h + 1)/(G + t) t = (h + 1)/G t = (h - 1)/(G + t) t = (h - 1)/(G - t) ANSWER DOWNLOAD EXAMIANS APP
