om being in a line with the sides of the reservoir. From the table we shall find 398 X 1-25 = 622-5 litres forthe discharge with a vertical orifice and complete contraction;consequently, 622-5 X 133 = 828 litres will be the effectivedischarge sought. 347. When vertical floodgates have their lower edges verynear the bottom of the reservoir, as is generally the case, to deter-mine the discharge, Multiply the numbers given in the table by 1-04. Example.—AVhat is the volume of water discharged per secondby a sluice, the orifice of which is opened to a height of -38 mlhaving -8 m. in width, and 2-5 m. being the distance from thecentre to the upper level? The table gives 1,599 litres for the discharge effected throughan orifice of a metre in width. Whence 1,599 X 8 X T04 =1,330-6 litres, the effective discharge sought. When two sluices are at not more than three metres distancefrom each other, and are open at the same time, the discharge willbe obtained by Practical Draughtsman. Plate 30.
