Project title: Connecting smart-high visibility clothing to construction site's network.

Need 6 summarize with the reference.

Calculate the head loss if the water is discharged through a 2,000 ft 8” steel pipe and a 1,500 ft 6” cast iron pipe at the discharge rate of 1.63 cfs;

The 8 inch pipe has a square-edged entrance; a swing check valve; fully opened gate valve; contraction (20 degree);

The 6 inch pipe has 6 - 45 deg. elbows; 2 - 90 deg. bends; 1 r=1 ft; 1 r=2ft.

Use Hazen-Williams equation to calculate the head loss of the straight pipes - C_h= 110 for steel and 120 for cast iron. Also list the minor loss coefficient

Philosophical/Engineer Question

Q1: Is discipline a responsibility?

Q2: Are consumers rational people

Q5:How is the code of ethics established for engineers?

The undrained strength of a clay is 1.2 kips/ft2 , the water table in 4 ft below the ground surface, the total unit weight of the clay is 118 lb/ft3 , and a round shallow foundations with a diameter of 4.25 ft is placed at a depth of 10 ft supports a column load. a. Use a factor of safety of 2.8 and compute the safe column load on the foundation. b. An excavation near the drilled shaft removes the soil down to the water table. What is the effect on the factor of safety? (Hint consider what the physical meaning of the components in the Hansen equation. Which component is impacted by the excavation?)

a. Explain the factors based on which the nominal cover for the reinforcement is decided.

b. What the value of k indicates in the calculation for area of steel and what if the value is k=0.268 in the design of slab.

c. What provisions will you implement if the slab becomes unsafe in the check for shear

Q1) Design a concrete mixture proportions which will be used for offshore concrete platform. Norway is a world leader on offshore concrete platforms with 1a of the world’s 30 larger offshore concrete structures located on the Norwegian continental shelf. The first of these platforms where the Ekofisk Tank installed in 1974 and the last was Troll gravity based structure installed in 1996. The Sakhalin project is located in a harsh and artic environment where concrete structures have proven excellent characteristics with a minimum of maintenance. 80 mm slump value is required for the Sakhalin project. 28-days concrete characteristic strength is 2b MPa. It is required that no more than 1 test result in 100 will fall below the specified strength. The fine aggregate has a fineness modulus of 2.60 and Zone 3. For Coarse Aggregate (Uncrushed): SSD Bulk Specific Gravity: 2.65, Absorption Capacity: 2.b %, Total Moisture: 1.c % and Dry Rodded Unit Weight: 1345 kg/m3. For Fine Aggregate (Uncrushed): SSD Bulk Specific Gravity: 2.70, Total Moisture: 3.d % and Free Moisture: 2 %. Cement: Portland Composite Cement, Specific Gravity: 2.97. For 0.e5 m3 of concrete, binder amount is calculated as 120 kg (Use ACI Method of Mix Design)

Mr. Joshua Lacey set the track record in a meet at LSU. For this achievement, he gets to choose
between a $250 cash prize paid immediately or $30 per year for 10 years. He already has
enough money for now so he decided on the 10 annual installments. However, he is considering
the following two investment options:
a. Save the winnings for the first 3 years and then spend every cent of the winnings in the
remaining 7 years that is collected.
b. Spend everything for the first 3 years then save the remaining 7 years of winnings collected.
i). Draw the cash flow diagram for each option (a) and (b).
ii). Also, if Bank plus is advertising that they can give him a savings ROR of 11% per year, how much
would each option (a) and (b) payout after the installments end? (10 pts)

Describe the process flow of sand casting to make flanges

Suppose you observed vehicle arrival flows in a single approach for two consecutive cycles at a signalized intersection. The signal has a 60 sec. cycle time with a 30 sec. green interval and a 30 sec. red interval (ignore yellow interval). The arrival rates are assumed to be constant in both cycles. The arrival rate was 720 veh/hour. Assume that the vehicles in the queue formed on red pass through the intersection during the subsequent green interval at the saturation flow rate of 1800 veh/hour immediately after the start of the green interval.

(a) Draw the queuing diagram for the approach during the two cycles

(b) Calculate the total uniform delay per cycle.

(c) Calculate the average delay per vehicle.

(d) Calculate the maximum queue length (i.e. maximum number of vehicles in the queue).
