Some areas of the Earth receive more solar radiation than others. Which of the following results from the Sun's uneven heating o

STatiana [176]

Some areas of the Earth receive more solar radiation than others and this Sun’s uneven heating of the Earth result in 

i. Climate

ii. Weather

iii. Ocean currents

Further Explanations:

Earth receives varied amount of solar radiation in its different parts. The situation is due to the orbicular shape of the Earth and inclination of the sun during different time of the year. We can see one such example that, during June sun is overheard Tropic of cancer and during September it is overhead Tropic of Capricorn. Because of the inclination,different regions of the Earth experience different climate at the same span of time. This unevenness results in the following phenomenon:

i. Climate:Climate is a continuing average weather condition of a place. Some of the climatological variables commonly measured to determine the climate temperature, moistness, atmospheric pressure, current of air, and precipitation.

ii. Weather: It is defined as the state of atmosphere, describing the degree of heat or coldness, wetness or aridness, calm or stormy. It also refers to daily temperature and rainfall activities.

iii. Ocean Current: It is more or less perpetual or continuous engaged movement of oceanic water flowing on the Earth’s oceans. The current gets created as the resultant of geological forces acting on the oceanic surface.

Chloroform flows through a 4.26 inch inside-diameter pipe at the rate of 3.60 gallons per minute. What is the average velocity o

Pani-rosa [81]

Answer:

1) 0,081 ft/s

2) 0,746 lb/s

Explanation:

The relation between flow and velocity of a fluid is given by:

Q=Av

where:

Q, flow [ft3/s]
A, cross section of the pipe [ft2]
v, velocity of the fluid [ft/s]

1)

To convert our data to appropiate units, we use the following convertion factors:

1 ft=12 inches

1 ft3=7,48 gallons

1 minute=60 seconds

So,

$Q=\frac{3,60 gallons}{1 min}*\frac{1min}{60 s}*\frac{1ft3}{7,48gallons}=0,00802 \frac{ft3}{s}$

As the pipe has a circular section, we use A=πd^2/4:

$d=4,26 inch *\frac{1ft}{12 inch}=0,355ft\\ A=\pi \frac{0,355^{2} }{4}=0,0989ft2$

Finally:

Q=vA......................v=Q/A

$v=\frac{0,00802ft^{3} /s}{0,0989ft^{2} }=0,081ft/s$

2)

The following formula is used to calculate the specific gravity of a material:

SG = ρ / ρW

where:

SG = specific gravity,

ρ = density of the material [lb/ft3]

ρW = density of water [lb/ft3] = 62.4 lbs/ft3

then:

ρ = SG*ρW = 1,49* 62,4 lb/ft3 = 93 lb/ft3

To calculate the mass flow, we just use the density of the chloroform in lb/ft3 to relate mass and volume:

$0,00802 \frac{ft3}{s}*\frac{93lb}{1ft3}=0,746lb/s$
