1.Determine the maximum possible precipitation at New York City that may be encountered on a 100 mi^2 drainage area over a 96 hr period.
2.By continuous discharge measurements the discharge in stream was determine over a 3-year period. After the data were assembled, it was found that the discharge exceeded 120 cfs 3 percent of the time; it exceeded 60 cfs 35 percent of the time; it exceeded 20 cfs 80 percent of the time; and the minimum discharge was 5 cfs. Construct a discharge-duration graph for the average year. What discharge is available half of the time?
Determine the effective size as well as the uniformity coefficient and coefficient of curvature for each soil. Determine also the percentages of gravel, sand, silt, and clay according to (a) ASTM, (b) AASHTO, (c)USCS, and (d) the British Standard.
Beginning whith the 1-D, steady state, general mass(volume) balance equation Qin-Qout=0 derive the 1-D poisson equation.
Assume a value of B, compute the allowable bearing capacity, then solve for B. Show at least 1 iteration with whatever assumed width irrespective of whether or not you get the desired Factor of safety.
A steel tube has an outside diameter of 2.5 inches and an inside diameter of 2.375 (1/8" thick). If it transmits 35 hp when turning at 2700 rpm, what is the maximum shear stress
assume that the whole twisting moment is taken by the bone. If the humerus can withstand a shear stress Tmax=70.0 MPa, determine the maximum force the hand can apply without fracturing the humerus. The length of the forearm is 360 mm.
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.
