Solucionario Ingenieria Termodinamica Jones Dugan 134 [ Fresh ]
The query seems to combine two very different requests: a search for a specific thermodynamics solutions manual and a request for an interesting story. 1. Ingeniería Termodinámica (Jones & Dugan)
The "solucionario" (solutions manual) for Ingeniería Termodinámica by J.B. Jones and R.E. Dugan is a highly sought-after academic resource. It covers the problems found in their standard textbook, which is often used in mechanical and chemical engineering programs.
Availability: While the full solutions manual is often restricted to instructors, partial solutions and student-uploaded documents can sometimes be found on academic sharing platforms like Studocu or Scribd.
Physical Copies: Used copies of the book or related manuals occasionally appear on marketplaces like Mercado Libre. 2. An "Interesting Story"
Since the phrase "interesting story" was attached to your query, here is a short, relevant anecdote from the world of thermodynamics involving the Second Law:
The Demon of MaxwellIn 1867, physicist James Clerk Maxwell proposed a thought experiment to "violate" the Second Law of Thermodynamics (which says entropy always increases). He imagined a tiny "demon" guarding a door between two chambers of gas. The demon would open the door only for fast-moving molecules to enter one side and slow ones to enter the other, effectively lowering entropy without doing "work."
For decades, scientists puzzled over why this wouldn't work. The "story" was finally resolved with the realization that the demon must store information about the molecules, and the act of erasing that information from its memory generates enough heat to increase entropy, saving the Second Law.

Title: Looking for solucionario Ingeniería Termodinámica – Jones & Dugan, Problem 134
Post:
Hi everyone,
I’m currently working through Engineering Thermodynamics by Jones and Dugan and have gotten stuck on problem 134 (chapter depends on the edition – in mine it’s from the section on energy analysis/closed systems).
I’ve been trying to solve it step by step, but I’m not fully confident in my approach. Does anyone have access to the solucionario (solution manual) for this textbook, or could share how they solved problem 134?
The problem states (paraphrasing from memory, will update exact wording later):
A piston-cylinder device contains 0.05 kg of air at 300 K and 150 kPa. The air is compressed polytropically (PV^n = constant) with n = 1.2 until the volume is reduced by half. Determine: (a) final temperature, (b) work done, and (c) heat transfer.
I’ve applied the ideal gas law and polytropic relations, but my heat transfer sign seems off compared to the first law. I suspect I’m messing up the boundary work sign convention.
If anyone has the official solution manual (Jones & Dugan) and could post the solution to problem 134, or even just the final answers so I can check my work, I’d really appreciate it.
Also, if someone has a PDF of the full solution manual, please let me know – happy to trade resources.
Thanks in advance!
Reply from another user (possible help): solucionario ingenieria termodinamica jones dugan 134
I don’t have the official solucionario, but for problem 134 (assuming it’s the polytropic compression of air):
- Final temp: T2 = T1*(V1/V2)^(n-1) = 300*(2)^(0.2) ≈ 300*1.1487 = 344.6 K
- Work: W = (P2V2 – P1V1)/(1-n) – be careful with signs. For compression, work done on the system is positive if you use the sign convention W_in = +.
- Heat transfer: Q = ΔU – W (depending on sign convention).
If you post the exact problem statement from your edition, I can solve it explicitly.

The solution to problem 1.34 from Engineering Thermodynamics by Jones and Dugan
(often numbered similarly in textbooks like Moran & Shapiro) focuses on the static equilibrium of a piston-cylinder assembly. Problem Solution: Static Equilibrium of a Piston
To determine the mass of the piston when the system is in static equilibrium, we perform a force balance on the piston.
Identify the acting forcesThree main forces act on the piston: Atmospheric force ( Fatmcap F sub a t m end-sub ): Acts downward due to external pressure. Weight of the piston ( ): Acts downward due to gravity ( Gas pressure force ( Fgascap F sub g a s end-sub ): Acts upward from the air inside the cylinder.
Establish the equilibrium equationSince the piston is in static equilibrium, the sum of vertical forces must be zero:
∑Fy=0⟹Fgas−Fatm−W=0sum of cap F sub y equals 0 ⟹ cap F sub g a s end-sub minus cap F sub a t m end-sub minus cap W equals 0 Substituting pressure and area (
