A coal-fired 500 MW Power Plant has an efficiency of 35%, burns coal with an energy content of 10,000 BTU/lb, with 60% carbon content, 1.5% sulfur content. The coal burned produces 10% ash, and of the ash, 70% is fly ash.
A) What are the carbon emissions (in lb C/hr)?
B) What are the sulfur emissions if a 70% efficient scrubbe
C) What are the particulate emissions released if a 99% efficient scrubber is used (in lb Fly Ash/hr) is used (in lb S/hr)?
Answer:
carbon emission = 292,468.8 lb/hr
sulfur emission = 2,193.526 lb/hr
emission release = 3,412.13 lb/hr
Explanation:
given data
energy = 500 MW
efficiency of 35%
solution
As we know for generate 500 MW energy we need to generate 1706071225.06 Btu/hr.
for efficiency of 35% we need total energy is
total energy = 1706071225.06 ÷ 0.35
total energy = 4874489214 Btu/hr.
and
For 4,874,489,214 Btu/hr = 487,448 lb/hr
So, for coal has 60% of carbon
so carbon emission = 487,448 × 0.60
carbon emission = 292,468.8 lb/hr
and
Total sulfur emission = 487,448 × 0.015
Total sulfur emission = 7,311.72 lb/hr
70% of this sulfur is removed before emission so the sulfur emission is
sulfur emission = 7,311.73 × 0.30
sulfur emission = 2,193.526 lb/hr
and
The burned coal will produce 487,448 × 0.70 = 341,213.6 lb/hr fly ash.
so 99% of this amount will be removed before emission, so emission is
emission release = 341,213.6 × 0.01
emission release = 3,412.13 lb/hr

If a single family residence is constructed on the cleared lot what processes will control the surface runoff from the lot
Answer:
As the region is deforested, the topography, gravity, soil permeability and terrain slope will control the runoff, as well as the intensity of the rain.
Explanation:
Runoff occurs when water flows over a soil that is saturated, that is, soaked. What controls the runoff efficiently is the native vegetation of the place, however, when this area is cleared, the soil is completely at the mercy of saturation, causing the runoff to be controlled by topography, gravity, permeability of the soil and the slope of the terrain, as well as the intensity of the rain.
Which statement best describes the information
presented on the map of Africa?
The areas projected to have the least amount of
growth are in Central Africa.
The areas projected to have the greatest amount of
growth are located on the Northern coast.
Most African countries are projected to have at least
60 percent growth.
Most southern African countries are projected to have at least 100 growth.
Answer:
Most African countries are projected to have at least 60 percent growth.
Explanation:
Africa, as a continent, has a very high population growth. While all other continents experience decline or stagnation in their population growth, Africa is the opposite and it is the continent that manages to keep the global population growth. The main reason why Africa's population is growing at such a rapid pace in modern times is that it is the least developed continent that only now is experiencing economic growth, relative stability, and improved healthcare.
There are differences across Africa of course. The northern and southern countries tend to be experiencing declines in their population growth, though it is still on a good level. All other countries though, or rather the vast majority, have population growth rates from at least 60%, and some go above 160%, which is incredibly high.

Clear-cutting of forests: a. Removes the carbon tied up in the vegetation b. Increases the rate of erosion c. Causes the depletion of soil nutrients d. All of the options are correct e. None of the options are correct
Answer:
d. All of the options are correct
Explanation:
The clear cutting of forests refers to the removal of all the native vegetation of a forest, which remains without any vegetation cover and with the soil completely unprotected. This type of activity is very disadvantageous for the environment because it promotes soil erosion, decreases the absorption capacity of carbon dioxide, causes depletion of soil nutrients and removes all carbon trapped in the vegetation.

Two causes of tsunami waves are landslides and earthquakes in the ocean. Based on your past knowledge of these events, explain how they can cause a tsunami.
Answer:
Tsunami are waves caused by sudden movement of the ocean surface due to earthquakes, landslides on the sea floor, land slumping into the ocean, large volcanic eruptions or meteorite impact in the ocean.
Explanation:
I don't know if this answers your question, if not, sorry.
Around then, earthquakes frequently cause these landslides. When a mass of a swiftly moving underwater landslide reaches the sea or when water moves in front of and behind of it, a tsunami can be created.
What do you mean by the Tsunami?A tsunami, which is short for "harbor wave" in Japanese, is a sequence of waves in a body of water brought on by the displacement of a significant amount of water, usually in an ocean or sizable lake.
A tsunami can be produced by earthquakes, volcanic eruptions, and other undersea explosions that occur above or below the surface of the water.
Tsunamis often consist of a sequence of waves that arrive in a "wave train" and have durations varying from minutes to hours.
Although tsunamis only affect coastal areas, they can have a tremendous amount of destructive power and can have an impact on entire ocean basins.
Therefore, around then, earthquakes frequently cause these landslides. When a mass of a swiftly moving underwater landslide reaches the sea or when water moves in front of and behind of it, a tsunami can be created.

?
Answer: (2,9)
Explanation:
Given: A point (9,-1) is first translated by rule [tex]T_{-4,3}: (x,y) \to (x-4, y+3)[/tex] followed by rotation of 270° .
Rule of rotation of 270° :[tex](x,y)\to (y,-x)[/tex]
Image of (9,-1) after translation:
[tex](9,-1)\to (-9,-1+3)= (-9,2)[/tex]
Then, image after rotation of 270° : [tex](-9,2)\to (2,9)[/tex]
Hence, the image point of (9,-1)(9,−1) after the transformation [tex]T_{-4,3}[/tex] and rotation of 270° is (2,9).

walking or biking.
Answer:
C. Strip malls, big box retail stores, malls, and drive-throughs have been developed to accommodate shoppers driving automobiles.
Explanation:
Shopping has now evolved into complete new thing. Earlier there were markets which were not constructed permanently and there were small carts which used to gather at one place and people shop from there. Suburban shopping experience is completely different from the rural ones. There are malls, big retail stores which enable drive through facility for the visitors so they don't have to experience hectic shopping. The shopping is now eased by online system and the grocery and other basic need shopping can be done by sitting at home.
Answer:
The correct answer is C )
Strip malls, big-box retail stores, malls, and drive-throughs have been developed to accommodate shoppers driving automobiles.
Explanation:
Shops as it used to be have evolved. Suburban malls are evolving into regional mega malls which are situated by the road side or very busy locations.
Many of them have been modified to accommodate the increasingly busy nature of shoppers who just want to stop by, make a purchase and drive away with the least amount of time spent.
The demerit of this development is that older malls that have served communities for a long time are left to suffer as people gravitate to these new suburban centers.
To survive, older shopping malls must adapt or re-strategize by remodeling their facilities, if possible to meet the current trends.

The largest country, in terms of land area, of the Indian Subcontinent, is India. Thus option A is correct.
What is the Subcontinent?A component of a continental is referred to as a subcontinent if it has a diverse political, physical, or cultural and identity in addition to a sizable land surface that is somewhat larger than a continent. The Asia landmass, the biggest continent inside this world, includes the Indian subcontinent.
Considering India is a complete landmass instead of a territory, it is occasionally described to as a subcontinent. Although it is not as big as one, it has some features of one, hence it is not regarded as a continent. A continental is a region that is a component of a continent, which is a bigger large island composed of several nations.
Therefore, option A is the correct option.
