Page 92 - V = velocity of flow in feet per second D = diameter of pipe in feet.
Page 1-11 - 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 1-10 - In a needle valve, the hydraulic forces acting on the needle are approximately balanced so that the force required to move the needle through its entire travel can readily be provided by mechanical operation. However, to provide positive seating in the closed position to minimize leakage, a large force should be supplied.
Page 1-12 - 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 104 - 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 101 - 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 104 - 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 101 - 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...
