Discuss the Fundamental mechanisms for biodegradation of organic waste in a landfill.

The engineering calculation on the telecommunication project is needed to analyze the feasibility of the project and the total value of investments. As the Project Manager, you have to do the financial analysis of your telecommunication project to get the conclusion of whether this feasible to run the project or not. You have to prove your analysis by giving the project calculation in terms of Net Present Value (NPV), Present Worth Analysis, and Break-Even Point (BEP) based on the initial investment, % of interest, and the project period are given.

The Detail Situation:

The company is considering the installation of a high-end server for handling the system with the first initial cost [check point A]. This system will save $7,500,000 per year in spare part cost, but it will incur $2,750,000 in annual operating and maintenance expenditures. The salvage value at the end of the system’s X-year [check point B] life is [check point C].

At the end of the project, the company will invest the new server for the next X upcoming year [check point B] with initial the initial cost of $50,000,000. This new system will save $8,500,000 per year in spare part cost, but it will incur $3,850,000 in annual operating and maintenance expenditures. The salvage value at the end of the system’s X-year [check point B] is negligible.

There is another option to cover the requirement by combining 2 different situations. At the first X years [check point B], the company will rent a high-end server for handling system the rent cost $5,000,000/ year. There is no budget that needs to be allocated for spare part cost, and it will incur $1,500,000 in annual operating and maintenance expenditures. In the second period, the company will invest the new server for the next X upcoming year

[check point B] with initial the initial cost of $50,000,000. This new system will save $8,500,000 per year in spare part cost, but it will incur $3,850,000 in annual operating and maintenance expenditures. The salvage value at the end of the system is negligible.

If the company’s hurdle rate (MARR) is X% per year [check point D], which scenario that should be recommended for implementation?

Group C (att.list no 7- 9):

- The first initial cost [point A] = $35,000,000

- Project duration [point B] = 8 years

- The salvage value at the end of the system’s [point C] = $2.500,000.

-  (MARR) is = 12 % per year.

Challenge of using steel bar in simple/standard house (i.e. landed house or lowincome house).

Example of using steel bar in concrete (choose your own example including picture/drawing/sketch).

A new landfill site is to be designed with a projected life of 32 years for a population of 220000 generating 2.27 kg waste/capita/day. The density of the compacted waste is 537 kg/m3. The height of landfill cannot exceed 13 meters. Please use the knowledge of solid waste management (especially landfill design) to describe the area (width x length) required for that landfill, if:   
a. The landfill does not have slopes   
b. The landfill has slopes (3:1 ratio)

Rainfall induced slope instability is a common phenomenon for an area in tropic region. Please discuss why rainfall will trigger the slope instability. You may apply the concept of principle of effective stress while explaining the slope instability (if necessary). Propose ONE (1) method of slope protection work and briefly elaborate how to control or prevent this from happened (slope failure due to rainfall).

The tangents of a spiral curve intersect at an angle of 25°at STA 4+072. The radius of the central curve is 300m and the length of the spiral curve is 52.71m.

a.) Determine the external distance of the spiral.

b.) Determine the offset distance from the tangent to the start of the central curve.

c.) Determine the spiral angle from TS to SC.

d.) Determine the deflection angle from TS to SC.

e.) Determine the stationing where the central curve ends

A domestic wastewater with a flow of 1700 m3 / day will be treated in a biological treatment plant. Wastewater pre-settling tank effluent BOD value is 350 mg / L. If the volume of the biological reactor (ventilation reactor) is 500 m3, do you prefer a fully mixed or plug-flow reactor? Please explain the reasons.

A vertical summit curve has tangent grades of +2.5% and -1.5% intersecting at station 12+460.12 at an elevation of 150m above sea level. If the length of the curve is 182m: a. Compute the length of the passing sight distance.

b. Compute the stationing of the highest point of the curve.

c. Compute the elevation of the highest point of the curve.

Q) Determine using the NRC formula, the BOD5 of the effluent from a single-stage, low-rate trickling filter that has a filter volume of 1,500 m3 , a hydraulic flow rate of 0.26 m3/s, and a recirculation ratio of 1.5. The influent BOD5 is 360 mg/L. Would the single stage be sufficient to achieve the WHO BOD efficacy? If not how can you improve the system efficiency and provide the necessary calculations?

Q) A. Design a set of three rectangular grit basins with proportional flow weir for a plant which has a max flow of 97,500 m3/day, an average flow of 75,000 m3/day and a minimum flow of 30,000 m3/day. Make the max depth equal to the width. The design velocity (Vh) is 0.5 m/s. B. Design a set of three parabolic channel for the same flow rates and design velocity in branch A above.
