A nearly horizontal, 12 ft wide rectangular channel carries 60 cfs at a depth of 3 ft. the width of the channel is smoothly contracted to 6 ft at the downstream section.
(a) determine if the flow will choke and both the downstream and upstream water depths.
(b) if there is also a 1 ft high step up in bottom elevation at the contraction, determine if the flow will choke and both the downstream and upstream water depths
a. Use algebra and linearity of the expectation operator to find the answer. b. Explain how the transformation affects the drawing of the scatterplot we used to develop our understanding of covariance, and therefore why the answer to part a. shoul..
The beam is positioned such that the observer on the train measures an angle of 19 between the crossbeam and the floor of the train. At what speed would the train have to be traveling in order for an observer standing outside the train
A water jet of diameter 2 inches and speed of v=60 ft/s is filling a tank at a 70 degree angle. The tank has a mass of 25 lbm and contains 6 gallons of water. The water temperature is 70 degrees F.
Drawdown at an observation well 15 m from the pumped well is 3.0 m, and drawdown at a second observation well 150 m away is 0.30 m. find the hydraulic conductivity of the aquifer.

The rigid bar of negligible weight is supported as shown. Find the stress in each rod if the temperature rises DeltaT after a load P is applied. Use the following data: area of steal rod 320mm2, bronze rod 1300mm2, thermal expansion coefficient Al..
The rope is 16 m long and the tree limb is 8 m above the man's center of gravity where he holds the rope. Suppose that the man begins at rest right next to the child and backs away with an acceleration of 0.2 m/s^2.
A dam is inclined at an angle of 30o from thevertical and has the shape of an isosceles trapezoid 100 ft wide atthe top and 50 feet wide at the bottom and with a slant height of70 ft. Find the hydrostatic force on the dam when it is full ofwater?
Part B (Assignment): by trial and error, find the angle that will give the minimum force F to make a basket (hint: try 52 degrees)The trajectory of the ball will make a basket when x = L and y = Hb
a volumen of 20 cu ft of air at pressure of 50 psig is heated and expanded and to 30 cu ft and 40psig find the changes in the energy of air in jouls.
Plan your field geotechnical instrumentation scheme. Plot your instrumentation systems on a cross section of your embankment and fully justify your answer. Also remember that you need to obtain the maximum data with the minimum cost?
