Commonly Used Equations
A few of the most commonly used equations used
when dealing with engines are the equation for effeciency and the
coefficient
of performance. The effeciency of an engine (E) can be
best described as "the energy we get out of an engine divided by the energy
we put into the engine".
We can also evaluate this as:
The coeffiecient of performance is the inverse
of the effeciency of an engine:
