Answer:
i think it is A, i could not really understand your question.
Explanation:
just a question
(wheres the article?)
Total heat rejected by compressor = Heat rejected by compression + Heat rejected by intercooler
Heat rejected by compression :
Q = (y - n)/(y - 1) • W
Q = (y - n)/(y - 1) • R(T2 - T1)/(n - 1) ... (i)
Heat rejected by intercooler :
Q = Cp(T2 - T1) ... (ii)
Sum of (i) and (ii) :
Q = (i) + (ii)
Q = (y - n)/(y - 1) • R(T2 - T1)/(n - 1) + Cp(T2 - T1) ... (iii)
Remember that :
R = Cp - Cv
y = Cp/Cv
So :
R = yCv - Cv
R = Cv(y - 1) ... (iv)
Now, subtitute (iv) to (iii) :
Q = (y - n)/(y - 1) • Cv(y - 1)(T2 - T1)/(n - 1) + Cp(T2 - T1)
Q = (y - n)/(n - 1) • Cv(T2 - T1) + Cp(T2 - T1)
Q = [Cp + Cv • (y - n)/(n - 1)] • (T2 - T1)
Hope this help
Answer:
Explanation:
The turbine is modelled after the First Law of Thermodynamics:
The rate of heat transfer between the turbine and its surroundings is:
The specific enthalpies at inlet and outlet are, respectively:
The required output is:
Answer:
(C) The volume of an atom is mostly empty space.
Explanation:
Rutherford's nuclear theory:
Rutherford's performed an experiment with the help of alpha particle and gold foil film.By doing this experiment he concluded that
1.Mass and charge of an atoms is located in the nucleus.
2.Nucleus are surrounding by electron .Nucleus is a positive charge particle and electron is a negative charge particle.
According to Rutherford's nuclear theory,the volume of an atom is mostly empty space.
So option C is correct.
(C) The volume of an atom is mostly empty space.
