. consider the replacement of the 400 mw san juan thermoelectric power plant in puerto rico, which uses heavy fuel oil to genera

te electricity, with a solar photovoltaic farm. the oil plant has a heat rate of 10,811 btu/kwh and a capacity factor of 53%. a. for installation of south-facing fixed tilt pv arrays, with tilt angle equal to the local latitude in san juan, how many acres of collector surface area would be required to replace the generation from the fuel oil plant? assume that the photovoltaic cells have an efficiency of 17%. b. by how many acres can the surface area in part (a) be reduced if single-axis tracking is added (with the collector tilt angle still equal to the local latitude)? c. what will be the annual fuel cost savings ($) if the oil power plant is retired, if heavy fuel oil costs $290 per metric ton and has a heating value of 39,500 btu/kg?

Annual saving energy produced *cost of oil/heating value is

$ 10020.46177.

<h3>Latitude and longitude: what are they?</h3>

Latitudes are lines that are horizontal and show how far a location is from the equator. In relation to the meridian in Greenwich, England, longitudes are vertical lines that show the east and west directions. Latitude and longitude are used in conjunction to locate points or places on the globe by cartographers, geographers, and others.

Puerto Rico's capital city's latitude and longitude are 18° 27' 58.7988" North and 66° 6' 20.5956" West.

Local San Juan latitude divided by tilt angle equals 18.46 WBAN No. 11641 = for year = 5.5 provides information on solar radiation for flat plate collectors facing south with a fixed tilt.

KWh/m2/day = 5.5 KWh/m2/day (1 day =3600h)

Formula used-

Solar radiation at that place* Collector Area *Collector efficiency = Heat rate * Output

power*Capacity factor

1 KW= 3,412.14 BTU/h

Heat rate* output power* capacity factor = 10,811*400*10^3*0.53 BTU/h = 671699.2855

KW

Collector Area = 671699.2855*3600/5.5*0.17

= 25862218.48 m^2= 6390 acres

C.

Cost of oil = 290$ /10^3 kg

Energy produced= 400*10^3 KW = 1364856 *10^3 BTU/h

Heating value = 39,500 Btu/kg

Annual saving Energy produced *cost of oil/heating value

= $ 10020.46177

75kg man climbs a mountain 1000m high in 3hrs and uses 4100 joulse/min. (a) calculate the power consumption in watt, (b) what is
mr Goodwill [35]

Answer:

Explanation:

a) Power consumption is 4100 J/min / 60 s/min = 68.3 W(atts)

work done raised the potential energy

b) 75(9.8)(1000) / (3(3600)) = 68.055555... 68.1 W

c) efficiency is 68.1 / 68.3 = 0.99593... or nearly 100%

Not a very likely scenario.

Which of these is most likely to produce radioactive waves?
Ivan
<h2>Answer:</h2>

<u>A. A nuclear power plant</u> produces radioactive wave.

<h2>Explanation:</h2>

A plant in which a nuclear reactor is used as a source to produce heat is known as nuclear power plant. The heat formed by the reactor is used to form steam which can be used to drive turbines to produce electricity.

The coolant in reactor gets heated by the fission process taking place in the reactor. It is a cyclic process where the steam is condensed and reverted back. A nuclear power plant in active condition produce a small amount of radiation which can be sensed within a radius of 50 miles.

Draw a right triangle so that its hypotenuse is 600 ft. The adjacent side is below the vertical, and it makes an angle of 75° with the hypotenuse.

Let h =  height of the right triangle.
By definition,
sin75° = h/600
h = 600*sin75° = 579.555 = 580 ft (nearest ft)

Answer: 580 ft (nearest foot)
