3 Heat transfer - Let’s look at Q and W in the absence of internal irreversiblities - Let’s assume one -inlet one outlet control volume at steady state - Definition : comparison between idealized efficiency and actual efficiency - Identify the source or lower efficiency (irreversibilites) to maximize the actual efficiency.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
