A 1.6-m wide rectangular channel carries 1.8 m3/s at a depth of 0.85 m. The channel undergoes a smooth transition in which the channel bottom rises 15 cm and contracts to a width of 1.3 m. Assuming friction losses are negligible, determine the depth of flow at the transition.
Knowing that these forces are equivalent to a force-couple system at C consisting of the force C= (- 8 N)i+ (4 N)k and the couple Mc =(360 N ⋅ m)i, determine the forces applied at A and B when Az = 2 N.
A CMFR is to be designed to remove contaminant A from water with a steady-state efficiency of 95 percent. The decay reaction is zeroth order, with a rate constant of 0.1M/h. The inlet concentration of A is 0.5 M.
A car travelling at 60 mph in a construction area skids into a stack of concrete barriers. Skid marks leading to the crash measures 150 ft .
Consider your cooking gas contains 80% propane and 20% butane. While burning on a cooktop, assume it burns with 200% excess air. If no heat is lost, determine the maximum possible flame temperature.
Due to a street crossing a roadway, the elevation of the roadway at station 3 +413.760 must be at 129.388 m. Design the curve?
A thin-walled cylindrical tank of radius r is subjected simultaneously to internal pressure p and a compressive force P through rigid end plates. Determine the magnitude of force P to produce pure shear in the cylindrical wall.
Determine the unstretched length of spring AC if a force P = 110 lb causes the angle theta = 60^circ for equilibrium. Cord AB is 2 {rm ft} long. Take k = 50;{rm lb/ft}
Determine the COD, carbonaceous BOD, and nitrogenous oxygen demand of a 100 mg/L solution of urea (N2H4CO)
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..
Determine the differential settlement between the centre line of the ring beam and under the centre of beam. The inner and outer radii of the ring beam are 8m and 12m respectively.
The cost of a 100,000 bbl/d ethanol unit is $40,000,000. From historical records, the capacity exponent ratio for CCR is 0.75. Estimate the cost of a similar ethanol unit with a capacity of 135,000 bbl/d.
The elevation of the lowest bottom of the structure is at 1470 feet. Calculate the maximum length (feet) of the parabolic curve required to meet the given conditions.
