The Wilson Wastewater Treatment Plant currently provides primary treatment for a flow rate of 2500 m³/day. The effluent from the primary tank has a soluble BOD₅= 240 mg/L. You need to design an activated sludge treatment to update the plant. The secondary effluent standards to meet are 25.0 mg/L BOD₅ total (suspended and soluble BOD) and 30 mg/L suspended solids. Use the following assumptions:

• Target soluble BOD₅ in the effluent of the secondary treatment is 2.5 mg/L.
• Growth constants can be estimated as K_s=145 mg/L BOD₅; k_d=0.025 d^-1; m_m=8 d^-1; Y=0.8 mg VSS/mg BOD₅ removed.
• The designed MLVSS is 3,000 mg/L.
• The settler is designed to achieve 12,000 mg SS/L in the settled sludge.
• The MLVSS fraction of MLSS is expected to be 0.7

A cantilever of circular solid cross section is fixed at one end and carries a concentrated load P at the free end. The diameter at the free end is 200mm and increases uniformly to 400 mm at the fixed end over a length of 2m. At what distance from the free will the bending stresses in the cantilever be maximum? Also calculate the value of the maximum bending stress if the concentrated load P=300 KN

(a) 1.23 m, 12.32 MPa

(b) 1.5 m, 11.23 MPa

(c) 1.0 m, 11.32 MPa

(d) 1.33 m, 13.42 MPa

Block B is initially at rest. Then block A slides on the smooth surface to the right and collides with block B with a velocity vAvA. Consider three following collision cases where: i) elastic impact; ii ) perfectly plastic impact; iii ) e = 0.5. Just after the collision, rank these three cases where the relative velocitiy of B with respect to A is from largest to smallest magnitude.

- When subcritical flow goes over a step down, does the kinetic energy increase, decrease or remain constant?

- You have subcritical flow going through a channel constriction that does not influence upstream water levels. If the critical depth is observed in the constriction, the minimum specific discharge is passing through the constriction

True or false?

- Subcritical flow encounters a step up transition that is smaller than the maximum step height. Does the specific energy:

- In supercritical flow that does not encounter a hydraulic structure, the upstream water is influenced by downstream conditions.

True or False?

Calculate the monthly average evaporation to occur from the surface of the water in open July, taking into account the following data for a lake,
£ using the Penman method.£
Latitude: 40.5 N.
Monthly Avg. Temperature: 21.3 C.
Real daylight hours: 9.8 hours
.2m wind speed: 145 km / h.
Albedo: 7%.
Relative Humidity: 55%

no sir it is homework I have to solve it by penman rules

#1 You are overseeing the plans for construction of a new highway. Someone proposes using cheaper, substandard materials to control/treat water flowing off the construction site. The water on the construction site contains measureable concentrations of sediments, oils from vehicles, heavy metals, and components of asphalt. A recreational lake is nearby and downgradient from the construction site. This is a substantial slope (10% grade) across the site.

Parts pertaining to #1:

a) LIST the three pillars of sustainability and EXPLAIN how this issue connects to each pillar.

b) Assuming you are a licensed engineer, what is your ethical obligation to the public AND other licensed engineers working on this job? [Your response should cover ethical obligations to both parties.]

Will like right away!!

3)Descriptive calls are given considerable weight when there are ambiguities.

True

False

4)
