A 3000 MWt fast reactor has a 42% efficiency. This reactor operates for 23 months followed by a 1 month down time for refueling
n200080 [17]

Answer:

capacity factor = 0.952

Availability factor = 0.958

Explanation:

1) capacity factor

capacity factor = actual power output /  maximum power output

                        = (actual power output)/(efficiency * rated power output)

                       = \frac{1200}{\frac{42}{100}*3000}

= 0.952

2) Availability factor

Availability factor  = Actual operation time period/ total time period

                            = 23/24 = 0.958

Luba_88 [7]

D. It is the heat required to change a gram of substance from a liquid to a gas.

Explanation:

The heat of vaporization is the heat required to change a gram of substance from a liquid to a gas.

  • It is also known as the enthalpy of vaporization.
  • The heat of vaporization is the quantity of heat needed to change one gram of a substance from liquid to gas.
  • This heat of vaporization is dependent on the pressure conditions the process is taking place.
  • Different liquids have their heat of vaporization.

desicribe the relationship between an inner planets distance from the sun and its period of revolution?
Anit [1.1K]

Kepler’s third law exhibits the relationships between the distance of a planet from the sun and the period of its revolution. Kepler’s third law is also sometimes referred to as the law of harmonies.

Kepler’s third law compares the orbital period and the radius of an orbit of a planet to the distance of the planet to the sun. It states mathematically that the more distant a planet is from the sun the greater its orbital period will be. The period of revolution of a planet is measured in days, weeks, months or years. For example, Earth’s period of revolution is 365 days.
