As a student of the civil engineering department, how could you benefit in the real-life professions from studying the curse of professional practices and business communication?

Generally, how reliable are Shear Box Tests for dry sand? What are common factors in the testing procedure or design which influence reliability? How can one tell if results are reliable? In general terms, as normal force is increased on a sample, what can be expected?

This is a rock mechanics question.Civil Engineering subject.
1 a)What is meant by systolic association of rock fracture.What is the application of popping of rock in oil industries?

Answer only if you are 100%sure otherwise I will give negative feedback.
Explain with neat diagrams the systolic association of rocks with respect to the locking and popping theory?

This is Civil Engineering questions

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).

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.
