A sluice gate partially extends down into the flow within a rectangular channel. The upstream water depth is 10 ft and the downstream depth is 4 ft. The gate is suddenly opened high enough to cause a 45% increase in discharge under it.
i) Determine the initial specific discharge under the gate.
ii) Write out (but don't solve) the continuity and momentum equations that govern the surge travelling downstream. (Note: assume that the surge velocity exceeds the water velocity)

Determine the deflection of a simple uniformly loaded beam by the Ritz method,using first one term, then two terms, adn finally three terms in a sine series. Why does the coefficient of sin2piex/L vanish?
A car is traveling up a 3% grade on a road that has good, wet pavement. The engine is running at 2500 rpm. The radius of the wheels is 15 inches, the driveline slipage is 3% and the overall gear reduction ratio is 2.5 to 1
Draw the shear diagram for the shaft. The bearings at and exert only vertical reactions on the shaft
A trapezoidal channel of bottom width 25ft and side slope 1:2.5 carries a discharge of 450cfs with a normal depth of 3.5 ft. The elevations at the beginning and end of the channel are 685 and 650 ft, respectively.
