Sustainable Concept

Air pollution in Asia has worsened since 2000 and is responsible for deaths of thousands of people in Beijing, Jakarta, Seoul and Manila. The pollution is a result of the use of fossil fuels by the industry and transport sectors. The problem got aggravated in Asia due to the use of poor quality fuel, inefficient method of energy production, use of vehicles in poor condition and traffic congestion. This was revealed during a research conducted by World Bank and Stockholm Development Institute. The research states that air pollution in the continent has surpassed the combined emissions in Europe and North America. The deaths caused by fine particulate matter far exceed those caused by sulphur dioxide, nitrogen oxide, ozone and lead. The health cost in major Asian cities now exceed for 15-18 percent of urban income expenditure, claims World Bank officials.

a) A comprehensive campaign to address air pollution need to be launched through school children, what programme (one) would you envisage for this. What is outcome anticipated?

b) There is a sudden decision to remove all vehicles from the road that fails to meet specified norms of emission level within a specified time period. As part of citizen forum you are requested to give views on the enforced regulation. State your views on this.

c) A massive campaign on environmental degradation is to be initiated. Bring out a slogan and the key message that need to be addressed.

d) Suppose you are a Carbon Credit Auditor appointed to assess the greenhouse gas emission reduction strategies. Identify a component of assessment and brief the methodology that could be adopted in connection with this.

Discuss the effect of reservoir fluid properties on completion design

Will the time frame of a project affect the completion design? Discuss.

Discuss the challenges posed by the drilling activities on reservoir completion.

List three common examples of how we use the low stiffness of polymers to our great advantage in numerous applications. In each application, explain how the polymer’s low stiffness comes into play. In your common examples, you are looking for applications that rely on a small amount of elastic deformation to perform their function properly.

The following data on chlorine dioxide added as a disinfectant to water

Determine:  

a) The decay rate, k* of chlorine dioxide in this water

b) The initial dose of disinfectant C_o that pathogens in the water would experience

c) The immediate demand C_ID for chlorine dioxide if 3.0 mg/L is the dosage.

For analyzing a bridge, bending moment diagrams were plotted for a simply supported beam of span 5 m when subjected to a uniformly distributed load of magnitude ‘w’ kN/m over the entire span. It was noted that maximum bending moment is equal to 37.5 kNm. Suggest a value for ‘w’ based on the requirements. How it will change the reactions at the supports? What happens to the shear force and bending moment values at the supports and at the center? By plotting bending moment and shear force diagrams for the beam briefly conclude the relationship between the
values for shear force and bending moment.

What consequences does a client face when a mishap occurs in a project? Please give a detailed answer.

Results obtained from a tension test on a bar of uniform cross section 10 mm x 10 mm subjected to an axial pull of 8000 N were tabulated. The lateral dimensions of the bar were found to be changed to 9.9985 mm x 9.9985 mm while using a material having modulus of rigidity equal to 0.8 x 107 N/cm2. By determining the values for different moduli, identify the properties of material and establish the relationship between them. What changes will happen to the volume if the length of the bar is equal to 2.5 m? Based on the results obtained discuss how the elastic constants are related to the deformation of the bar?
