Popular passages
Page 96 - V = velocity of flow in feet per second D = diameter of pipe in feet.
Page 1-12 - A coaster gate consists primarily of a skin plate supported by horizontal beams which, in turn, are supported by vertical girders at the sides. Continuous roller trains are mounted around the vertical...
Page 1-1 - The needle is moved by water pressure from the outlet conduit which acts on interior chambers in the valve. The movement is controlled by a...
Page 1-2 - Tube valves are ordinarily better adapted to underwater discharge or for use inside a conduit, since an insufficient air supply does not appear to produce all the cavitational effects inherent in other valves.
Page 108 - The pier must be stable against sliding. The vertical component of the resultant of all forces should not be less than the horizontal component of all forces divided by the coefficient of sliding friction at the base of the pier. The friction coefficient may vary from 0.35 to 0.65, depending on the underlying material. The base of the pier should be placed below the frost line. Steel reinforcement of concrete piers is usually limited to that required for temperature and shrinkage crack control.
Page 105 - The clearances at the ends of the sleeves and the distances from the ends of the sleeves to the packing- retainer rings should be ample to permit the maximum movement expected.
Page 108 - The vertical component of the resultant of all forces should not be less than the horizontal component of the resultant of all forces divided by the coefficient of sliding friction at the base of the anchor.
Page 105 - This consists of an inner and an outer sleeve, a stuffing box with packing, held by a retainer ring and compressed with a packing gland. The inner...
Page 1-24 - The reservoir water, when allowed to flow into the recess chamber, will cause pressure on the bottom face of the gate, thereby rotating it slowly upward about the hinge-pin until raised.
