Relation Between Efficiency

In accordance with the significance of physics, the basic difference that has been shared by the two terms such as efficiency and the coefficient of performance, the coefficient of performance generally takes the output based on what output has been intended to be seen. On the other hand, it has been found that the output of the efficiency has been calculated based on the provided input. Based on this general difference between efficiency and the coefficient of performance, the current study will discuss the definition of both terminologies. Along with that, the relation between these two terminologies will be represented as well. The relation between the power factor and efficiency has been stated in the study too. 

Definition of efficiency

In reference to the terminology of physics, the most common definition of efficiency refers to the particular indication that helps to indicate how well the energy that has been provided can be converted into useful work. As per the definition of thermodynamics, it has been considered that the machines are made with an intention of wasting little energy as per the possibility. This particular fact states that the input energy needs to be possibly transferred mostly into useful energy stores. Based on this particular explanation, it can be described in a simpler manner that efficiency has been referred to as how good a device is able to transform the input energy into useful output energy. 

Definition of Coefficient of performance

In accordance with the terms of thermodynamics, the coefficient of performance has been referred to as the ratio of the useful cooling or heating provided to the work required. As per the terminology of physics, a higher rate of COP represents higher efficiency. That means the device has a lower operating cost and the machine consumes lower energy. In a simpler language, the definition of the coefficient of performance has been recognised as similar to the thermal efficiency of a heat engine. 

Explanation of efficiency

Based on the facts related to thermodynamics, it can be stated that a good device wastes vary little of the energy that has been input into the device. On the basis of this concept of efficiency represented by thermodynamics, it can be proposed that efficiency can be represented in a number of percentages or in decimal numbers. Based on the formula, efficiency can be calculated by dividing the value of useful energy transferred from the total value of supplied energy. Then the result needs to be multiplied by 100 in order to get the percentage of efficiency.

Explanation of COP

As per the representation of coefficient of performance, the value of this particular term has been represented as an equation that is Q divided by W. In this specific representation of the calculation process of the coefficient of performance, the word Q has been referred to the heat that has been removed or supplied by the considered system. On the other hand, the W represents the network that has been put into the considered system in one cycle. 

Relation between power factor and efficiency

The power factor has been referred to as an expression of the efficiency of the energy. This particular value has been represented as a percentage. Based on this factual knowledge, it can be stated that the lower the percentage of the power factor the power efficiency will be lowered in a similar manner. The power factor is basically a ratio of working power to apparent power. Therefore, it can be seen that this particular terminology of physics shares a relation with efficiency. A direct relation has been shared between these two concepts of thermodynamics. 

Difference between efficiency and COP

The main difference between these two terminologies lies in the definitions. 

• The efficiency has been represented as the ratio between work output and heat input
• The coefficient of performance has been represented as the ratio of the desired effect to work output. 
• The efficiency has been calculated by dividing the output by input, on the contrary, the formula for calculation of the coefficient of performance is Q/W where the Q is heat and the w represents the work output. 

Conclusion

In order to sum up all that has been discussed so far in the present study, it can be stated that the main discussion of the study was based on the explanation of efficiency and the coefficient of performance. These two terminologies of physics have been explained and exemplified as well in the discussion part of this study. Moreover, the formula of efficiency has been mentioned and discussed as well. The formula related to the COP has been discussed too along with the explanation of the relationship that lies between the power factor and efficiency. On the other hand, the difference between the coefficient of performance and the efficiency has been discussed in the current study as well.
