The flow hydrograph ordinates observed in a basin with a precipitation area of 500 km2 for a
3-hour showers are given in the table below. Assuming the base flow is constant and 10
m3/h;

a) Calculate the total volume of flow as m3, which consists of precipitation.
b) Calculate excess rainfall height and duration.
c) Determine the unit hydrograph which is equal to the precipitation period of excess
rainfall.

(time is given a hour 10m3/h ) not false..

The distance and depth values measured in various slices in a stream section and the measurement times and rotation numbers in a muline with coefficients a = 0.15 and b= 0.08 are given below.
a. Calculate the area, average velocity, and flow rate of each slice as well as the total area and average velocity of the entire cross section.
b. When measuring with another muline, it was measured as n = 22 when V = 1.94 m/s and n = 28 when V = 2.14 m/s. Determine coefficients of muline and equation of velocity. In a measurement made with this muline, calculate the flow rate according to making 35 rotations to the muline in 55 seconds.

A nonslender square corner column is subjected to biaxial bending about its x and y axises. It suppoerts a factored load  Pu= 300,000 lbs acting at eccentricities e_x=ey= 7 in. Design the column size and reinforcement needed to resist the applied stresses. Given: f'c = 4000 psi fy = 60,000 psi. d'=2.5 in. Gross reinforcement percentage, p_x=0.03. Solve by using all three methods.

Some advocate for small scale wind turbines, for instance, on buildings in urban areas etc. An advantage would be more distributed generation, close to usage (reduced transmission loss etc.) Comment on ‘micro-wind’ projects from an engineering perspective (scaling, physics etc.)

Design a nonslender column to support the following service loads and moments. The factored ultimate axial force P₁= 100 kips, PD= 100 kips, ML= 2500 in.-kips, and MD= 1000in.- kips,. The eccentricity e to geometric centroid = 6 in. Given: f'c = 4000 psi fy = 60,000 psi.

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.
