Page 448 - Specimen bars of the metal used, each being 26 in. long by 2 in. wide and 1 in. thick, shall be made without charge as often as the engineer may direct, and, in default of definite instructions, the contractor shall make and test at least one bar from each heat or run of metal. The bars, when placed flat-wise upon supports 24 in.
Page 622 - CONVENIENT EQUIVALENTS The following is a list of convenient equivalents for use in hydraulic computations: Table for converting discharge in second-feet per square mile into run-off in depth in inches over the area NOTE. — For partial month, multiply the values for one day by the number of days.

Page 532 - At least one tensile and one bending test shall be made from each melt of steel as rolled. In case steel differing | in.
Page 444 - The valve must be faced with a yielding material, such as rubber or leather, except that, if of the gate type, a bronze ring may be used.
Page 249 - ... being at from 61 to 65 per cent for the pump used in the Wisconsin experiments. At other submergences the output varies as the ordinates of a parabola having a vertical axis. Under these conditions the lift does not remain constant as the percentage of submergence varies. 6. The length of pump and percentage of submergence remaining constant, and therefore constant lift, the efficiency increases as the input decreases; that is, the highest efficiencies are obtained at the lowest rates of pumping....
Page 444 - When packing nut is used, it must be made of bronze or suitable non-corrodible metal. The bottom of the box and end of the gland or packing nut must be slightly beveled.
Page 80 - As the size increases beyond this point, the velocity with a given head does not increase as rapidly as the square of the effective size ; and with coarse gravels the velocity varies as the square root of the head instead of directly with the head as in sands. The influence of temperature also becomes less marked with the coarse gravels.
Page 227 - This consists of a cylinder of steel or iron 1 to 2 feet long, split along one side and slightly spread. The lower portion is very slightly expanded, sharpened, and tempered into a cutting edge. In use it is attached to a rope or wooden poles and lifted and dropped in the hole by means of a rope given a few turns around a windlass or drum.
Page 671 - ... other manner of disposal of the excreta collected as aforesaid, which is not specifically approved by the State Board of Health after due submission to said board, the said excreta shall be disposed of by digging the same into the surface soil or by burial in trenches of moderate depth in places where the character of the subsoil and the depth of the ground-water level will afford ample security both against the undue pollution of such ground-water and the soil itself, and for the efficient filtration...
