Explain the details of ductility with moment-curvature relationship with an example and drawing moment – curvature diagram.

1. Compare the volume occupied by 1000 lb of refuse before (loose) and after baling by calculating the compaction ratio.

a. List waste densities (loose and baled) and provide a reference.

b. Calculate the compaction ratio.

Refuse composition (percent by weight)

how is sludge treated differently in water treatment vs wastewater treatment?

A department in the facility required 12,250 units of raw materials to produce a TV. The company is deciding wither to buy or make raw materials. The fixed and variable cost of building (manufacturing) the raw materials are $20,000 and $5, respectively. Also, the fixed and variable costs for buying the raw materials are $400 and $7, respectively. Use the breakeven analysis methods to decide if the company has to purchase or manufacture the raw materials.

Describe the concrete mix design concerns when a contractor elects to use a hydraulic pump to place concrete

1. Name two supplementary materials and explain where they come from .

2. Discuss the differences , advantages and disadvantages of the wet and dry process of cement production.

3. List the main thermal zones in a cement kiln. Briefly describe the processes in each zone.

Please provide list of general areas that shall be covered by an Inspection Report by an Architect from Earthworks to Finishing.

1. A car idling emits NO_xat a rate of 2 g/sec. Assuming an effective “stack” (tailpipe) height of 2 feet, Class C stability, and a wind speed at tailpipe height of 0.5 m/sec, estimate the ground-level concentration of NO_x100 m directly downwind. Terrain is rural.

How to reduce Carbon Emissions while Excavating?

Q3. You have been selected to design a secondary wastewater treatment plant for a municipality in Amman of 15,000 people which has some industry that discharges wastewater to the municipal sewer system. The average daily wastewater flow is 2.1 MGD (million gallon/d) and the raw sewage entering the WWTP has an average BOD₅ of 240 mg/L and average suspended solids of 260 mg/L.

1. If the average domestic per capita sewage flow is 115 gpcd, what is the average flow of the industrial wastewater in MGD?
2. If the average BOD5 load from the domestic sewage is 0.18 lbs/capita-day, what is the average daily BOD5 loading (in lbs/day) from the industrial wastewater? What is the population equivalent to this BOD5 loading?

Q4. What are the quantitative requirements for BOD₅ and SS in wastewater discharges from secondary WWTPs? Hint:BOD₅ and TSS in the effluent must be less than or equal to 30 mg/L based on a 30 day average, and ≥85% removal of both must be achieved

Assume that you are a consultant for a city or community that is trying to put in place a long-term sustainability plan. You are fully in charge of making sure that all the key stakeholders are invited, involved, engaged and heard throughout the process. On this Discussion Board, I would like you to comment on how you would go about ensuring that process. You may choose a state/city/community and environmental/socio-economic problem of your choice.

When boiling​ water, a hot plate takes an average of 7 minutes​ [min] and 25 seconds​ [s] to boil 150 milliliters​ [mL] of water. Assume the temperature in the lab is 72 degrees Fahrenheit ​[Superscript o Baseline Upper F​]. The hot plate is rated to provide 592 watts​ [W]. If we wish to boil 150 milliliters​ [mL] of acetone using this same hot​ plate, how long do we expect the process to​ take? Acetone has a boiling point of 56 degrees Celsius ​[Superscript o Baseline Upper C​]. ​[Hint: you must determine the efficiency of the​ hotplate.]
