Water is the working fluid in an ideal rankine cycle. saturated vapor enters the turbine at 16 mpa, and the condenser pressure is 8 kpa. the mass flow rate of steam entering the turbine is 120 kg/s. determine:

(a) the net power developed, in kw.
(b) the rate of heat transfer to the steam passing through the boiler, in kw.
(c) the thermal efficiency.
(d) the mass flow rate of condenser cooling water, in kg/s, if the cooling water undergoes a temperature increase of 188c with negligible pressure change in passing through the condenser.

a.) travels faster in solids because the particles are closer together.

air is a gas water is a liquid

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.

causes

fossil fuels burn

cities become more industrialized

human population grows worldwide
