Irrigation Engineering If D is the depth of water upstream of the throat above its sill, B is the width of the throat, to achieve critical flow in an open venturi flume, the theoretical maximum flow Q, is Q = 1.71 BD3/2 Q = 1.71 BD Q = 1/71 BD2/3 Q = 1.71 BD1/2 Q = 1.71 BD3/2 Q = 1.71 BD Q = 1/71 BD2/3 Q = 1.71 BD1/2 ANSWER DOWNLOAD EXAMIANS APP
Irrigation Engineering The consumptive use of water for a crop Is measured as the volume of water per unit area May be supplied partly by precipitation and partly by irrigation All of these Is measured as depth of water on irrigated area Is measured as the volume of water per unit area May be supplied partly by precipitation and partly by irrigation All of these Is measured as depth of water on irrigated area 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) 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 ANSWER DOWNLOAD EXAMIANS APP
