Asteam power plant operates on as illustrated in the figure below (follow the numbers from the problem statement not the figure), however it only includes one feedwater heater. steam enters the turbine at 4,500 kpa and 500 c and exhausts at 20 kpa. steam for the feedwater is extracted from the turbine at 350 kpa, and in condensing raises the temperature of the feedwater to within 6 c of its condensation temperature at 350 kpa. if the turbine and pump efficiencies are both 0.78, what is the thermal efficiency of the cycle and what fraction of the steam entering the turbine is extracted for the feedwater heater? note.- i would suggest you use the figure to create your own with the information from the problem statement.

explanation:

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
