Water flows under a sluice gate on a horizontal bed at the inlet to a flame. upstream from the gate, the water depth is 1.5 feet and the speed is negligible. at the vena contracta downstream from the gate, the flow streamlines are straight and the depth is 2 inches. determine the flow speed downstream from the gate and the the discharge in ft^3/s per foot of width. how deep is the water to produce two times of the speed obtained?

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.

Different types of steels contain different elements that alter the characteristics of the steel. for each of the following elements, explain what the element does when alloyed with steel.
