Yes, this new cycle is not a Carnot cycle, and it works between the same heat reservoirs defined in this post : it takes heat from a hot reservoir at Ta and rejects heat to an huge number of cold reservoirs ranging from Tb1 to Tbn.

Mason, suppose you design a new cycle that operates between the same heat reservoirs specified in the beginning of this thread. ¿ Which of the infinite possible combinations of the set of Carnot Cycles should we use for comparison?

Andrew Mason, I understand your argument, but do you believe that the infinite set of Carnot cycles have diferent efficiencies according to the heat distribution, or , at the end, when you average all of the possible combinations, you will get only one value, equal to Eav= 1- ( Tb1+Tbn)/2Ta...

Yes, Andrew Mason, what happen if the amount of heat transferred to each cycle is different?. From above equations It appears that the average efficiency depends on the way we transfer heat. Above equation sugests that if we transfer a great amount of heat to the lowest cold reservoirs we...

lalbatros, let me rewrite the problem: we have a set of n parallel carnot cycles: the first carnot cycle takes an amount of heat Qa1 from a hot reservoir at Ta and expells an amount of heat Qb1 to a cold reservoir at Tb1 doing a work equal to W1. The second carnot cycle takes an amount of...

Please, excuse me, but I made a mistake writing the equations of the efficiency. The correct form is the following : E1= 1-Tb1/Ta E2= 1-Tb2/Ta E3=1-Tb3/Ta En=1-Tbn/Ta

Appreciated members of this forum: Suppose we have an infinite set of n carnot cycles and we know the efficiency of each cycle of the set: E1,E2,E3,E4,E5,,,,,En , where En is the efficiency of the nth cycle. E1= 1-Ta/Tb1 , E2= 1-Ta/Tb2, E3= 1-Ta/Tb ... En=1-Ta/ Tbn Ta is the...

Analizing your discusion, there is an additional restriction that I did not mention in my original thread. The requirement is that to each nonzero small segment of the line we have to associate by a one to one transformation a number 1,2,3,4,5...n where n is a huge number near infinite...

Dear friends, I have asked the following question before, but I am not still satisfied with the answer given by the experts of this forum. In Einstein equation E=m/c2 ¿ Does E equal to the thermodynamic internal energy of matter plus kinetic energy plus potential energy of a system?. ¿...

Dear people of this forum, Assume we have an interval of a line [ a, b]. Now, let us divide this interval in many ( infinite ) subintervals of finite size. ? What will be the size of these many intervals, equal or unequal, when the number of subintervals tends to infinite?. ¿there is any...

In relation to my question, If I use equal weights , do this means that, statiscally, we are using a distibution which is not oriented to one side or another, or that it is not biased?

Would you please, explain me why it is so?

Dear people of this forum Let us suppose we have infinite functions of the form F= w1 X1 + w2X2+ w3 X3 + w4 X4+... Where w1,w2,w3, w4 are variable weights and X1, X2, X3, X4 are fixed temperatures. Now, I have to choose one of the above infinite functions with the requirement...

For a pure sustance the variation of the Gibbs free energy, dG, is equal to dG= VdP-SdT where V,P,S,T are volume, pressure, entropy and temperature, respectively. At constant T, above equation becomes dG= VdP For an ideal gas PV=...

I think, this is , almost a phylosophical question. What is behind of all the galazies, beyond the limits of everything?. The quantum vacuum?, The nothingness?, what crossess the boundaries of the universe? work?. heat,?, cosmic rays ?. Subtle radiations? what is it beyond?. Anyway. it looks...
