Assuming 800 W / m 2 solar irradiance and a 35 % efficient solar panel, how much roof area should be covered to supply 10 A at 1

Korvikt [17]

Answer:

a) 4.286 m² b) $ 55.44/mo

Explanation:

If we assume that the sun is behaving as an isotropic radiator, the power density that is arriving to the house, is constant and equal to the quoted solar irradiance.

If the energy conversion capability of the solar panels were 100%, the roof area needed to supply the power required, would be simply the quotient between the power required and the solar irradiance, as follows:

A = P / SI = 10 A* 120 V / 800 W/m² = 1200 W / 800 W/m²= 1,5 m²

As the solar panels are only 35% efficient in converting the solar energy to useful electrical energy, we will need more roof area, according to this expression:

Ae = At / 0.35 = 1,5 / 0.35 = 4.286 m²

b) If we can get 1200 W during 7 hs/day, the energy supplied by the solar panels will be the product of the power times the time, as follows:

E= 1200 W* 7 hs = 8.4 Kwh

If the cost per Kwh, is $0.22, assuming 7 hs. of use in average during a month (assumed to be of 30 days), we can have savings as follows:

Cost = 0.22($/Kwh)* 8.4 (Kwh/day)*30 (days/mo) = $ 55.44

The shear flow at the point depends on the value of Q for the portion of the upper flange to the right of the point. Calculate t

Ostrovityanka [42]

Q)The shear flow at a point is given by q = 1 of 2 An I-beam has a flange width b = 200 mm , height h = 200 mm , web thickness tw = 8 mm, and flange thickness t = 12 mm, For the given point The shear flow at the point depends on the value of Q for the portion of the upper flange to the right of the point. Calculate the value of Q. Express your answer with appropriate units to three significant figures.( I have also attached the diagram for better understanding)

Answer:

Q = 56400 mm^3

Explanation:

I have given the explanation in the attached file below.

When it is 2 PM Mountain Standard Time (MST) on February 3 in North Platte, NE(L = 101◦ W, φ = 41.1◦ N), what is the solar time?

barxatty [35]

Solar time for

North Platte is 13.02

Boise is 13.02

Eastern daylight time is 12.48

Central daylight is 12.06

Explanation:

6 hours "central standard time" is the standard time zone. The saving time of daylight is + 1 hour. current time zone is the 5 hours central daylight time.
7 hours is the mountain standard time. The saving time of daylight is + 1 hour. current time zone is the 6 hours central daylight time.
5 hours is the eastern daylight time. The time shifts to +1 hour forwarded to eastern daylight zone and GMT is behind 4 hours.
5 hours is the central daylight time. The GMT is behind 5 hours during summer season

A four-cylinder four-stroke engine is modelled using the cold air standard Otto cycle (two engine revolutions per cycle). Given

suter [353]

Answer:

56.47%

Explanation:

Determine the efficiency of the Engine

Given data : T1 (k) = 325, P1 (kpa) = 185,

V1 (cm^3) = 410 , r = 8, T3(k) = 3420

speed ( RPM) = 4800

USING THIS FORMULA

efficiency ( n ) = $1 - (\frac{1}{(rp)^{r-1} })$

= 1 - $(\frac{1}{(8)^{r-1} })$ = 1 - (1/8^1.4-1 )

= 0.5647 = 56.47%

explain how a roller coaster functions using gravity and momentum. Why does it not need an engine or a motor to speed it up and

vichka [17]

Answer:

A roller coaster does not have an engine to generate energy. This builds up a supply of potential energy that will be used to go down the hill as the train is pulled by gravity. Then all of that stored energy is released as kinetic energy which is what will get the train to go up the next hill.
