Answer:
power produced = 3098.52 kW
Explanation:
given data
insulated turbine = 100 bar
temperature = 400°C
pressure = 200 kPa
mass flow rate = 1.99 kg/s
solution
we use here steam table for At 100 bar and 400°C
h1 = 3096.5 KJ/Kg
and
at P2 = 200 Kpa
h2 = hf + 0.47 hg
h2 = 504.7 + 0.47 × 2201.6
h2 = 1539.452 KJ/Kg
so here
power produced is express as
power produced = m × (h1 - h2) .................1
power produced = 1.99 × ( 3096.5 - 1539.452 )
power produced = 3098.52 kW
Answer:
Explanation:
Simply put, a solar panel works by allowing photons, or particles of light, to knock electrons free from atoms, generating a flow of electricity. Solar panels actually comprise many, smaller units called photovoltaic cells. (Photovoltaic simply means they convert sunlight into electricity. The attached diagram give an ilustsration of the photovotaic pannel mounted on a roof top.
Solution
To Determine the electric power generated for
a) A still summer day.
E = A * r * H * PR
E = Total Amount of Energy in kilowatt
A = Total Surface Area
r = efficiency Rating
H = global radiation value
PR = Performance Ratio
kwh = watt * Time/1000
kwh = 100 * 35/1000
3.5
b)
kwh = watt * Time/1000
kwh = 30 *15/1000
4.5
Moisture content is measured in terms of pounds of water per pound of air (lb water/lb air) or grains of water per pound of air (gr. of water/lb air).

Answer:
Mass of earth will be 
Explanation:
We have given acceleration due to gravity 
Radius of earth = 6370 km =
Gravitational constant 
We know that acceleration due to gravity is given by
, here G is gravitational constant, M is mass of earth and R is radius of earth
So 
So mass of earth will be
Answer:
starburst
Explanation:
There are many different kinds of "hazard symbols," which are being used in order for people to recognize what kind of material they are handling. When it comes to "pictograms," the symbol for a hazard class of explosive is an exploding bomb that shows a<em> starburst effect.</em> An example of such chemical is the <em>"organic peroxide" </em>and other<u> self-reactive chemicals.</u>
A "flame" is a hazard symbol for<em> flammable substances</em>. A<em> </em>"gas cylinder" is a hazard symbol for <em>gases that are located in containers that are under pressure.</em> A "test tube" is a hazard symbol for <em>substances/materials that cause corrosion to skin.</em>
