Meets for 3 hours of lecture and 1 hour of discussion each week for 10 weeks.

Contributes toward the Mechanical Engineering Topics courses and Major design experience. Contributes toward the Aerospace Engineering Topics course and Major design experience.

Discussions are held in the lectures and homework problems include how to use the principles of thermodynamics in the design of many engineering applications that involve heat transfer and work. Examples are: power generating systems for electricity, production (power stations), jet engines and reciprocating engines, in addition to refrigeration systems.
