Design a broad crested weir for a laboratory flume with a width of 1.25 ft. The discharge range is 0.1 to 1.0 cfs. The maximum approach flow depth is 18 inches. Determine the height of the weir P and the weir length l in the flow direction. Assume cv =1.
determine the force in member AC, FH, and FG and indicate if the member is in tension or compression. List all zero force members.
Due to a crash at a railroad crossing, an overpass is to be constructed on an existing level highway. the existing highway has a design speed of 50 mi/h.
A hypothetical water treatment train consisting of coagulation/flocculation unit, filtration unit and chlorination system is used to treat surface water characterized by bacterial concentration of 800,000 CFU/L.
Water flows past a triangular flat plate oriented parallel to the free stream. Integrate the wall shear stress over the plate to determine the friction drag on one side of the plate. Assume laminar boundary layer flow.
Three stock car drivers are racing around a circular bend. They are each circling the bend at different radii: r(1)=249 m , r(2)=255 m , and r(3)=261 m . At a given instant, all three are traveling at the same transverse rate of rotation
Estimate the median and 90th percentile load of SS contained in the runoff. Note: COV = coefficient of variance

The cart takes 5.00s to go from point A to point C, and the cart takes 1.90s to go from point B to point C. What is the cart's speed at point B. Express answer numerically to three significant figures in feet per second.
A log that is 2 ft in diameter is to be cut into a rectangular section for use as a simply supported beam. The material is wood select structural grade (Douglas Fir) with a specific gravity of 0.017 lb/in3.
Concept of CSTR, A lagoon is to be designed to accommodate an input flow of 0.10 m^3/s of nonconservative pollutant with concentration 30.0mg/L and reaction rate 0.20/day
A proposal has been submitted to replace a group of assembly workers, each working individually, with an assembly line. The following table gives the individual work elements. The demand rate for this job is 1600 units/week (assume 40h/week)
The size of the house is 28ftx40ftx10ft. For simplicity, assume the roof is flat, covered with 1-in plywood plus asbestos shingles and has 3 1/2 in of fiberglass insulation. There is a wood subfloor (25/32 in) in the attic and a ahrdwood floor (3/..
