Sometimes a person needs answers, it would seem, for primitive questions, but I want to say that many people know that many answers do not know. Today, we quickly run on the calculation of the efficiency, which in the decrypted form sounds like a efficiency.
Concept of efficiency
In order to deal with his calculation of this indicator, it is necessary to begin to understand what this concept is and, so to speak, with which it is eaten. So, here are some decodes of the concept under consideration (such a list makes it possible to understand the whole essence of the efficiency, that is, everyone will choose the concept that it will be clear to him):
The effectiveness of any device (whether the machine, system, etc.) in relation to the energy transfer or its transformation. It is possible to determine it by the ratio of used energy to the total energy volume obtained by the system.
If we talk about the efficiency in electrical engine engines, it can be said that this indicator is considered as the ratio of the operation of a mechanical type to the energy of an electric type.
Thermal type engines are a ratio of mechanical work, but already to a thermal volume that is spent.

CPD calculation
Often in everyday life there is a need to evaluate the effectiveness of any mechanism, that is, how effective is its use, as well as how appropriate.
It turns out that it becomes necessary to calculate what proportion of all perfect work was made in vain, so to speak, and what benefit. It is in order to be able to calculate this indicator, and a useful coefficient has been created.
η \u003d (or_apt / A_Polesn) * 100%
All the designations are quite clear:
- Appeapt - total work
- And useful - work is useful
Now you know how to calculate the efficiency.
