A coal fired plant burns 1000 metric tons of coal per day at 2% sulfur. ( 1 metric ton = 1000 kg). a. What is the SO2 emission rate? b. What is the SO2 concentration 1.0 km downwind (x = 1000m)? c. 0.1 km off centerline in y direction (y = 100m)? and d. At ground level (z = 0) wind speed is 4 m/s and it’s a cloudy day? Stability =D; σ_y = 68m; σ_z = 37m

Urbanization involves the growth of cities, flow of traffic, transportation assets, facilities and fixed infrastructure. Collectively, these factors play major roles in what has become to be known as a “four-stage” process of urbanization. Smooth traffic flow enhances to a significant extent the urbanization process in cities, and by implication, government activities and private enterprise. Based on your course readings and knowledge of the concept of urbanization, graphically illustrate the four-stage process typically associated with this phenomenon tagged “urbanization” detailing the essential factors from stage one to stage four.

to justify and defend recommendation of solid waste management and sewerage characteristic,
treatment and its disposal according to standards/practices .

1.Problem statement:
People are facing lot of problems due to improper management of wastes (solid) as well as
unsuitable characteristics, disposal and treatment of sewerage wastes. Using the knowledge
of solid waste management, characteristics, treatment and disposal of sewerage, find
various parameters required for proper management of solid wastes as well as for
characteristics, treatment and disposal of sewerage wastes for your area.
2. Objectives of this Project:
Students should use their background knowledge about solid waste management and sewerage
characteristic, treatment and its disposal. They should prepare a report to ensure that all the
parameters are properly addressed and incorporated.

3. Report Format
The report should include the following sections:
4. Problem Definition/Identification:
This is a statement of the problem to be investigated. It provides overall direction for problem
understanding. The student should rephrase the stated problem in his own words that can display
his understanding of the problem.
5. Details of processes involved:
Students must provide all the details of processes involve in solid waste management and each
process must be clearly supported by steps necessary for performing them.
6. Propose Solution:
This is a statement which should provide a clear solution (solid waste management) to the problem.
7. Conclusions:
Discuss any questionable data or surprising results. Explain the possible source of any error or
questionable results, if applicable.

(a) When there is a need to describe a system at the current time or at a certain specified future time, why are probabilistic models considered superior to deterministic models? (b) What is the difference between descriptive models and prescriptive models? Give two examples of each.

CCG, limited owns an office building in west Amman. The Company decided to change 10-year-old carpets, install new wall coverings and drapes in the office building two months back. Some of the employees are complaining for the last two months of headaches, nausea etc. The president of the company thought that by installing the new carpets, it would improve the working environment for the employees. But now she has started doubting her judgment. You are asked to make recommendations to remedy this situation? Elaborate your response focusing on the sources of pollution and an action plan including options to mitigate the problem if you know that the possible cause is VOCs (Formaldehydes, likely from new materials).

1. Which parameters control the dynamic behavior of sandy and clayey soils? State them separately for sand and clay.

A multilane highway has two northbound lanes. Each lane has a capacity of 1500 vehicles per hour. Currently, northbound traffic is consists of 3100 vehicles with 1 occupant, 600 vehicles with 2 occupants, 400 vehicle with 3 occupants, and 20 buses with 50 occupants each. The highway’s performance function is

t = t₀ ( 1 + 1.15 (x/c)^6.87 )

where t is in minutes, t₀ is equal to 15 minutes, and x and c are volumes and capacities in vehicle per hour. An additional lane is being added with 1500 veh/h capacity. What will the total person hours of travel be if the lane is

(a) open to all traffic,

(b) open to vehicles with two or more occupants only, and

(c) open to vehicles with three or more occupants only? (Assume that all qualified higher-occupancy vehicles use only the new lane, no unqualified vehicles use the new lane, and there is no mode shift.)

Which would be the best sound insulator for filling opening the concrete wall opening - wood, fiberglass insulation or steel and why?

A hazardous material spill on Interstate I-76 caused the eastbound traffic 20-minute delay. Traffic flow is completely shut down on a three-lane section creating a jam density of 160vpm/lane. If the arriving flow on this roadway section is 3300vph at a density of 35 vpm/lane, determine the following:

a) the total number of vehicles in the queue and the queue length (miles) after 20 minutes.

b) spacing (in ft/Veh) between vehicles in the jammed traffic.

c) if the roadway is re-opened after 20 minutes and the releasing flow at the bottleneck is 1800vph/lane at a density of 60vpm/lane, how long will it take for the releasing wave (moving upstream from the bottleneck) to catch up with the jam density shockwave?

1. A) Describe Moody’s chart and its importance in your own words. Also explain how do you find the friction factor by using the chart?

B) If the friction factor is 0.04 and the relative roughness is 0.004 then find the type of flow? (1 mark)
