1) For each of the conduits, s elect suitable gates and/or valves, on the locations stated below. Select operating mechanisms and briefly describe gates/valves selected. For Tower Irrigation intake: - On intake: One maintenance - On outlet: One service and one emergency For Chute Spillway: One maintenance and one service For Orifice Spillway: - On intake: One emergency - On outlet: One service and one emergency IRRIGATION TOWER INTAKE (A) CHUTE SPILL WAY (B) POWER PLANTE INTAKE ORIFICE SPILLWAY (^) BOTTOM OUTLET PENSTOCK POWER PLANT C.7-Q.6 For Power Plant conduit: - On intake: one emergency Upstream of Turbine: One emergency For Bottom Outlet conduit: - On intake: One maintenance - At middle: One emergenc y and one service 2) To have a discharge capability of 100 m3/s under effective head of 150 meter, what should be the: a) Diameter of a Howell Bunger valve, with discharge coefficient of 0.55. b) Dimensions of a Slide gate, with discharge coefficient of 0.9.(assume gate height to be 1.2 time gate width). 3) What should be the minimum disc diameter for piston of a double acting hydraulic servomotor of 100 metric ton capacity(shown here), with hydraulic working pressure of 80 bar. Assume diameter of piston rod to be 0.2 time diameter of piston. (ignore friction).
