A concrete mix with a 3-inch slump, w/c ratio of 0.50, and sand with a fine- ness modulus of 2.4 contains 1700 lb/yd3 of coarse aggregate. Compute the required weight of coarse aggregate per cubic yard. To adjust the mix so as to increase the compressive strength, the water-to-cement ratio is reduced to 0.45. Will the quantity of coarse aggregate increase, decrease, or stay the same?
A company facing an interest rate of 8% must choose among projects offering the following four-year cash flows. If the company is employing the net present value criterion, which project should they choose
A trapezoidal canal 6m wide at the bottom and having a side slope of 1V:2H carries water with a mean velocity of 1.0m/s to a depth of 60cm. What length of contracted rectangular weir 1.0m high should be placed at the middle of the canal to make th..
Biological treatment processes for wastewater can be catogarised as dispersed growth and attached growth systems. Discuss the advantages and disadvantages of attached growth systems over dispersed growth systems.
A simple curve has a central angle of 42degreess. A point Y is located 24m from the vertex and has a perpendicular distance of 3.00m from the back tangent.
A reverse osmosis plant desalinates 5X10^6 L/day of feedwater containing 1500 mg/L of salts, yielding 3X10^6 L/day of product water with 75 mg?l of salt. What would the salt concentration be in the brine?
