The involves building a 80 feet highX80X100 foot in dimension reinforced concrete structure with 3 - foot thick walls in the river that extends to twenty feet below river bottom in soft clay. Water depth at the location is 30 feet. The structure starts at 200 feet from the river edge where land is about 5 feet above the river level.The project needs to be completed in 800 days. Determine the amount and types of equipment you feel should be used on this project

A Simply supported rectangular, tension-reinforced beam is to be designed for dead load of 0.75 k/ft plus self weight and service live load of 2.0 k/ft, with a 30 -ft simple span. Material strength will be fy = 60 ksi and fc = 5 ksi for steel and normal weight concrete respectively.

Start the design of the beam dimensions using the rules of thumbs in class. The total beam depth, h, must not exceed twice the width.

Calculate the required beam dimensions and tensile steel requirement (As required) to carry the Maximum moment found at mid span. Start with a steel ratio of half of "usable rho" in Table 27.2 in the text. Use ACI load factors and strength reduction factors. The effective depth (d) may be assumed at 3 inches less than the total depth (h).

Draw a sketch clearly showing spacing, cover, and bar locations.

An electrostatic precipitator is to be designed to collect dust from a pulverized coal boiler with an actual flow of 100 m3/s. The effective migration velocity for the flyash is anticipated to be 0.08 m/s. The design gas flow velocity is 1.2 m/s, the plate height is 10 m, and the plate-toplate spacing (2s) is 0.25 m.

a. Determine the number of ducts required to accommodate the flow [-].

b. For an efficiency of 99%, determine the required plate length [m
