An 18-inch storm drain (n=0.013 | s=0.025) is designed to discharge 9.75 CFS. The design guidelines state that the velocity can not exceed 10 ft/s in the pipeline. What is the velocity in the pipeline?
Which type of ripple marks would you expect to see on the bed of a river - Describe the sediment that forms.
Fluid flows steadily, at a volume rate Q, through a large pipe and then divides into two small pipes, the larger of which has an inside diameter of 25 mm and carries three times the flow of the smaller pipe.
At compressor exit, the specific entropy is the same as that at the inlet, and the pressure is 60 psia. Determine the R-134a exit temperature and the change in the enthalpy of R134a.
Your engineering consulting firm has been asked to determine the specific weight of an unknown material. You decide to use the concept of buoyancy to figure this out. So you weigh the material in both air and water.
Five million gallons per day (mgd) of a conservative substance,with concentration of 10 mg/L is released into a stream having anupstream flow of 10.0 mgd and a substance concentration of 3 mg/L.Assume complete mixing.
The center of gravity of the crane is 10 ft from the pin, and the crane weighs 200 lb. What is the tension in the horizontal cable.
A pumped storage power plant is to be designed for a flow rate of 6,000 cfs per penstock. The penstocks are 20 ft. in diameter, with a relative roughness of 0.008. The elevation difference between the two reservoirs is 340 ft.
Let X be a uniformly distributed continuous random variable ranging between 5 and 8, X ~ U[5 , 8]. Variable Y is a function of X: Y: h(X)= 2X^2+1 a. Determine the PDF of Y. b. Find the expected value of Y.
Using a safety factor of two based on the stress, determine the maximum temperature the component must be exposed to for it to sustain the stress for at least 1000 days.
Prepare an outline of the experimental design you will suggest to the plant manager. This outline should contain research rationale, aims and objectives, research methodology, nature of data analysis and interpretation, and possible outcomes/concl..
The 24-in pipe leads from a reservoir (flush entrance), and the 18-in pipe discharges into the air at a point 15 ft lower than the reservoir water surface level. Assuming all changes in section to be abrupt
A bicyclist travels on a level path. The frontal area of the cyclist and the bicycle is 2.3 ft^2 and the drag coeffcient is 1.2. The specific weight of the air is .075lb/ft^3. How much horsepower (1hp=550ft*lb/s) does the cyclist need to produce to m..
