9. The following data are given for an activated sludge process: BOD5 (influent) = 250 mg/L (soluble) BOD5 (effluent) = 20 mg/L (soluble) MCRT = 10 days MLSS in the aeration tank = 2500 mg/L Concentration of SS in the recycle line = 10,000 mg/L Concentration of SS in the effluent = 30 mg/L (70% biodegradable) BOD5/BODu = 0.75, No nutrient limitations. Yield co-efficient, Y = 0.65 Endogenouse decay coefficient, kd = 0.06/day , Q=5MGD

Determine:
(a) Find soluble BOD5 (in mg/L) in the effluent, BOD5 treatment efficiency (in %) and overall efficiency (in %)
(b) Find hydraulic detention time (in hours) and the volume of tank (in MG).
(c) Yobs and biomass production (in lb VSS/day) (d) Qw (in MGD) when the wasting from the AT and from recycle line. (e) Recirculation ratio (f) Find Specific Utilization rate (U) and food to microorganism (F/M) ratio (g) Calculate volumetric loading rate (lb BOD5 /1000 ft3)

[HCM for Basic Freeway Segments] A six-lane freeway (three lanes in each direction) operates at the maximum service flow rate (MSF) of LOS D conditions during the peak hour with an observed demand volume of 3500 veh/h (one direction). The free flow speed (FFS) of the freeway is estimated to be 65 mi/h. The freeway is on rolling terrain and the traffic stream consists of passenger cars and buses only. The PHF is 0.85 and the traffic is all commuters. If a new busway was open next to this freeway and all buses were removed from the freeway, the new demand volume is 2354.55 (veh/h) for this freeway segment. Assume that car traffic remains the same.

What would be the LOS under the new demand volume? Note that this new demand volume now consists of passenger cars only as the buses were removed from this traffic stream. Assume that the freeway operates under ideal conditions (no incidents, work zones, or weather events).

Explain how Civil Liberties and Civil Rights address global warming through carbon emissions (300 words).

A Portland Cement Concrete (rigid) pavement is to be designed using AASHTO empirical design method. The pavement should have an 8" granular sub-base having elastic modulus (E_sb) of 50x10³ psi. The resilient modulus of the subgrade is 5000 psi, and lying just 5 feet above rock strata (bed rock).

(a) Determine the design k value, assuming loss of support factor (LSF) of 2.

(b) Use the k value obtained from (a) to determine the thickness of the rigid pavement.  

Assume concrete elastic modulus (E_c) = 5 x 10⁶ psi , Modulus of rupture (Sc) = 650 psi, load transfer factor J = 3.2, drainage coefficient C_d = 1.0, present serviceability loss ∆PSI = 4.2 — 2.5 = 1.7, reliability R = 95%, standard deviation S_o = 0.29, and total ESAL W₁₈ = 5.1 x 10⁶.

The vulnerability of soil types to a mechanical stress process (same intensity and magnitude) is different. Explain why.

Determine the location of the shear centre of the C-shaped rolled-steel beam cross-section C150x19.3 with respect to the centre of the web. Indicate whether it is to the left or right of the centre of the web. Assume the section to be thin walled and neglect the rounding of corners.

Sedimentation basins are employed both in filter plants for drinking water treatment and in municipal wastewater treatment plants. Briefly explain what solids are removed in each of these sedimentation basins.

A vertical curve is designed for 90 km/h and has an initial grade of + 2.5% and a final grade of -1.0%. The PVT is at station 3 + 480. It is known that a point on the curve at station 3 + 440 is at elevation 75 m. What is the stationing and elevation of the PVC? What is the stationing and elevation of the high point on the curve?

An equal-tangent crest vertical curve is designed for 100 km/h. The initial grade is +3.4% and the final grade is negative. Draw the curve. What is the elevation difference between the PVC and the high point of the curve?

A vertical curve is designed for 75 km/h and has an initial grade of + 3.5% and a final grade of -2.0%. The PVT is at station 3 + 560. It is known that a point on the curve at station 3 + 520 is at elevation 85 m. What is the stationing and elevation of the PVC? What is the stationing and elevation of the high point on the curve?

i would really appreciated if answer this question quickly thank you all !

Think back to all of the ways we have learned to analyze structures by hand in this class. Now recall the SAP2000 assignments and any other software program we may have used (excel, maybe Mathcad or MatLab). Using at least 10 sentences, discuss how technology is making it easier and making it harder to complete structural analysis tasks. In what way does technology present new challenges? What are some of the advantages and disadvantages?
