Objectives: Students should be able to:
1. perform simple thermodynamic analysis of gas powered cycles such as the Otto, Diesel and
Brayton cycles,
2. perform simple thermodynamic analysis of Rankine cycles,
3. perform simple thermodynamic analysis of vapor compression refrigeration systems,
4. perform simple thermodynamic analysis of gaseous mixtures, and
5. perform simple thermodynamic analysis of combustion processes.
Topics: Review of Chapters 2-6, Chapter 8 – Gas Power Cycles (Otto & Brayton Cycles), Chapter 9 –
Vapor Power Cycles (Rankine), Chapter 10 - Refrigeration & Heat Pump Cycles, Chapter 11 –
Thermodynamic Property Relations, Chapter 12 - Ideal Gas Mixtures, Chapter 13 – Gas – Vapor Mixtures
& A/C, Chapter 14 – Combustion & Reacting Mixtures.
Absence Policy: If you must miss a class for a university approved reason, (religious holiday, documented sickness,
required military training, etc.), then you must contact me at doliver@eng.utoledo.edu or leave a written note with the
MIME secretary for me before hand. Everyone is allowed to miss one pop-quiz for an excused or unexcused reason.

Homework: 2, 12, 18, & 20
Additional Homework for Chapter 11:
A) Consider an ideal vapor compression cycle, using R-134a, acting between the
pressures of 0.1MPa and 1.0MPa. Find the COP. (Ans COP = 2.64)
B) Consider a two-stage cascade refrigeration system operation between the pressure
limits of 0.1MPa and 1.0MPa with an intermediate pressure of 0.4MPa. Assume that
each stage is an ideal vapor-compression cycle using R-134a. The mass flow rate in
the low pressure stage is 0.01 kg/s. Find the following:
a) the mass flow rate in the high pressure stage in kg/s (0.0134).
b) the rate of heat removal from the lower stage in Watts (1,694).
c) the rate of work in the low pressure and high pressure compressors in Watts,
(282 & 254).
d) the COP for the process (3.17).
