A pump is located 4.5 m to one side of, and 3.5 m above a reservoir. The pump is actually designed for a flow of 6 L/s, not the 6.5 L/s that is shown. For satisfactory operation, the static pressure at the pump inlet must not be lower than -6 m of water gage. Determine the smallest standard commercial pipe that will give the required performance.
Writing case study about bridge collapse
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.
A constant head permeability test was conducted on a clean sand sample. The diameter and length of the test specimen were 10 cm and 12 cm respectively.
Analyze the stability of the dam shown in the figure, if the friction coefficient between concrete and foundation is 0.70, and the specific weights of concrete and water are 24kN/m 3 and 10kN/m 3 , respectively.
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.
Prepare a capstone report for designing of steel building using AISC 14 edition manual.

Describe in your own words the three strengthening mechanisms i.e., grain size reduction, solid solution strengthening, and strain hardening. Be sure to explain how dislocations are involved in each of the strengthening techniques.
A tub of a washing machine is rotating at 50 rad/s when the power is turned off. If it takes 15s for the tub to come to rest, determine (a) the constant angular deceleration, and (b) the total number of revolutions the tub makes.
