pressure
Mean effective pressure
- Effective stroke
- Working or power stroke in a two-stroke engine
-
Effective temperature
- Overall effect on a human of air temperature, humidity, and air movement.
- Efficiency
-
- The accomplishment of something with the least amount of
effort, energy, or fuel.
- Output of a device, system, or activity, divided by the input
necessary to create the output. In a compressor the efficiency
would be the work output, as measured by pressure change,
divided by the energy input (usually electrical).
- The efficiency of an electrical motor is the ratio of
mechanical output to electrical input. It represents the
effectiveness with which the electrical motor converts
electrical energy into mechanical energy
- A measure (usually a ratio) of the useful energy provided by
a dynamic system versus the total energy supplied to it during
a specific period of operation.
