Thermodynamics (MECH 240 Thermodynamics 1)
Efficiency is a word that is often bandied about carelessly leading to ambiguity and meaningless assertions. So then, what is really meant by efficiency? How does one decide what is efficiency? What is efficiency measuring? As will be discovered in the four labs that follow, efficiency is really a catch-all term for a variety of parameters that measure a system's performance. Thus, there are many types of efficiencies, each one having its own significance. How they are applied, calculated, and interpreted is of the utmost importance to any mechanical engineer.
