The COP can be more that one since the heat transferred can be more than power required by the refrigerator but the efficiency can never be more than one since the power generated by engine cannot be more than the total heat content of the fuel.
why correlation cofficient always lies between 1 and -1
A budget "variance" is the difference between planned and actual performance.
What is the difference between statistics and parameter
difference between Data Mining and OLAP
What is the difference between the population and sample regression functions? Is this a distinction without difference?
Coefficient of performance, or COP, is defined differently for heating and cooling applications. For heating: COP=(heat supplied + work)/work For cooling: COP=(heat removed)/work Work in this case refers to the compressor and other motors.

Efficiency is like a ratio. The higher the efficiency the less you have to put in or the more you get out. Performance is just how fast or how much it can make of something. Example: A hybrid car has a high efficiency because you get more mileage than say a muscle car, but the muscle car has higher performance because it goes faster and has more power.
Clipless pedals can improve cycling performance and efficiency by allowing for a more secure connection between the rider's feet and the pedals, resulting in better power transfer and control.
no difference
Between efficiency and effectiveness which one is more important for performance
effectiveness refers to the ability to produce the desired results. efficiency refers to the correctness of the produced result ex; effectiveness is like making an engine of high performance and efficiency is like the extent to which it works and reach the goal of the manufacture
Efficiency refers to doing things in the most economical way possible, while effectiveness is about achieving desired outcomes. Organizations can strike a balance between the two by focusing on streamlining processes for efficiency and aligning goals with actions for effectiveness. This can be achieved through clear communication, setting measurable objectives, and regularly evaluating performance to make necessary adjustments. By optimizing both efficiency and effectiveness, organizations can improve their overall performance and achieve their goals more effectively.
When using a bike in high gear, you will have higher performance and speed, but lower efficiency. In low gear, you will have lower performance and speed, but higher efficiency.
Isentropic efficiency compares the actual performance of a compressor to its performance under ideal, frictionless conditions. In most cases, real-world compressors have inefficiencies due to factors like heat transfer and mechanical losses, resulting in lower compressor efficiency compared to isentropic efficiency. The difference between the two values reflects the losses and imperfections present in the compressor system.
The recommended e-bike wattage for optimal performance and efficiency is typically between 250 to 750 watts.
