Compute the normal depth in a rectangular wooden flume with base width of 2 ft, roughness of 0.020, and slope of 0.01 ft/ft if the flowrate is 3.5 CFS.
Find the settling velocity of a 20 µm diameter particle with density 1500 kg/m3. If this particle had been hurled to a height of 8,000 m during a volcanic eruption, estimate the time required to reach the ground
Lab studies have shown that the rate constant associated with the process are as follows: k = 0.95 mg COD/mg VSS-day; Y = 0.48 mg VSS/ mg COD, half-saturation K = 85 mg COD/L; ke = 0.07 d-1.
If all the posts have the same original lenth before they are loaded, determine the average normal stress developed in each post when post C is heated so that its temperature is increased by 20 degrees F.
Consider the simply supported beam that has one external load applied to it. At a cross- section that cuts through the carriage bolt, there are 5 points at which the states of stress must be identified.
Determine the drag force FD on a golf ball assuming it is a smooth sphere. (Assume the air is at 60 F and standard pressure.) Now determine the drag force on an actual golf ball assuming CD = 0.25. How do the two forces compare
Assuming the origin is placed where the bullet begins to move, the force (in newtons) exerted by the expanding gas on the bullet is 18000 + 7000x - 20000x2, where x is in meters.
Suppose there were reason to believe that incomes in some population were normally distributed, with a mean of $47,000 per year, and a standard deviation of $5,500 per year.
If a hose whose discharge end is left open on the ground is first connected to the lower valve and then to the higher valve, will there be any difference between the discharge rates of water for the 2 cases? Neglect frictional effects.
If an additional 11-ft lane is added (each direction) and all other factors stay the same, what will be the new level of service?
This unit enables learners to develop an understanding of the methods and techniques used to create civil engineering structures and the skills needed to solve problems associated with civil engineering activities
A drop of water forms under a solid surface. assume the drop has the shape of a hemisphere just before seperating. find an expression for the diameter, D
Workers plan to apply a reflective coating of paint to one surface of an equilateral triangular shaped highway sign. How many square inches of coating need to be applied to the sign if one side of the triangle is 12 inches?
