Describe the production of energy from municipal waste. Please find details below;

This is a PowerPoint presentation (or in PDF format) should include at least 15 slides but no more than 40. Important for me will be

Information should be correct

Data should not be too much obsolete

Don’t forget give the references

The presentation should be readable

A Student in mass transfer operation lab accidently spills 10 litres of gasoline, which quickly spreads over a level surface of area 10 m2 . Estimate the time required for the gasoline to evaporate into the stagnant air above the surface of the liquid. The diffusivity of gasoline in air is 0.65 m2 h -1 . The air temperature is 298 K. Evaporation may be assumed to take place through a film of air of 2 mm thickness. Vapour pressure of gasoline at 298 K is 76 mmHg. The density of gasoline is 720 kg m-3 and the molecular weight of gasoline is 200. The operation takes place at 1 atm pressure

Engineering chemistry problem.

In industry, an ethylene oxide is produced with air. Under operating conditions, much of the ethylene is converted to ethylene oxide, another part is fully oxidized to CO2 and water, and the rest is unreacted. The gases leave the reactor and go to an absorption column where the water will absorb all the ethylene oxide. The exhaust gases from the absorption column have 9.6% CO2, 6.4% C2H4, 3% O2, and 81% N2. % of ethylene entering the reactor is converted to ethylene oxide and what% remains unreacted? What is the ethylene / air ratio?

  Explain the following terms related to the water infrastructure and describe how they apply to water infrastructure: Safe Drinking Water Act (SDWA) of 1974, the Bio‐Terrorism Act of 2002, the WaterISAC, Hetch Hetchy, scarce resource.

A mixture of benzene and toluene boils at 95°C under a pressure of 101.3kPa. Calculate
the composition of the boiling liquid assuming the mixture obeys Raoult’s law. At 95°C,
the vapour pressure of benzene is 155.56 kPa and that of toluene is 63.98 kPa.

Explain why the terrestrial planets are so different from the gas giants.

Notice that I did not ask you to describe what the differences are but to explain why the differences exist.

1-Which U.S. President gave Rachel Carson's scientific findings vindication and went on to enact a ban on DDT? 1-Ronald Reagan 2-John F. Kennedy 3-Jimmy Carter 4- George W. Bush

2-DDT saved millions of lives during World War II. true or false

3-Carson was never subjected to ridicule and condemnation from the pesticide industry. true or false

4-While writing her book, Silent Spring, Rachel Carson was suffering from cancer. true or false

5-Carson expressed many times that she was not opposed to chemical sprays for the purpose of controlling pests. Rather, it was their "indiscriminate use" at a time when their wider effects were not well understood that she rallied against. true or false

4.   A pharmaceutical firm produces different brands of a drug; I, II, III and IV. Each brand contains volume(s) of at least one of chemical X or Y or both. Product I requires a combination of two centimeters square of chemical X and a unit square of chemical Y given a resource constraint of 16. A unit square of chemical X and two centimeters square of chemical Y is needed to produce product II given a resource constraint of 11. Product III needs only chemical X and requires at least two centimeters square volume of chemical X while product IV requires a unit centimeter square of chemical X and three centimeters square of chemical Y with a constraint of 15. The company makes a profit of ¢3000 for using a unit of X and ¢5000 for a unit of Y.
(i)   Write four inequalities involving X and Y that reflect the conditions above
(ii)   Determine, graphically, the best possible combinations of X and Y for the company.
(iii)   Using the objective function, determine the best combination that maximizes the company’s profit.                           25 marks

5.   SBL Ltd decided on the 5th of February to start producing bottled water. By 14th March, SBL Ltd had put all the needed structures at a cost of ¢1000 and indicated a profit before operation to be - ¢1000. They reported that the cost of producing any of their product depends on the function 3Q + 0.004Q2. SBL Ltd further, indicated that additional product produced increases profit by a margin defined by 7 – 0.012Q. Determine;
(i)   The total cost function of SBL Ltd
(ii)   The profit function of SBL Ltd
(iii)   The total revenue function of SBL Ltd (Hint: Profit = TR – TC)
(iv)   The output level that maximizes the firm’s revenue.
