# Thread: specific concept

1. ## specific concept

Hi,

We have a specific concept in Mechanical Engineering. This concept describes that when entropy generation increases, then first law of thermodynamics decreases. Now, according to following figure, Are following sentences good? Are the following sentence correct grammatically. If these are not , kindly suggest ways to make it clearer.

*Maximum first efficiency of thermodynamics is in good agreement with minimum entropy generation.
*Good agreement between the maximum first efficiency of thermodynamics and minimum entropy generation is created.
*Good agreement between the first efficiency of thermodynamics and entropy generation is created.

2. ## Re: specific concept

They don't read well to me. How about using correlation instead of agreement?

3. ## Re: specific concept

What do you add a "first" in the middle of "maximum efficiency"?

I don't know, Is "correlation" appropriate in this proposition ?

Hi,

Excuse me, I wrote wrong. In fact, It is first law efficiency of thermodynamics.

*Maximum first law efficiency of thermodynamics is in good agreement with minimum entropy generation.
*Good agreement between the maximum first law efficiency of thermodynamics and minimum entropy generation is created.
*Good agreement between the first law efficiency of thermodynamics and entropy generation is created.

Agreement isn't.

But I want to use this sentences in abstract of paper. In fact, there is not any plot in abstract, only I want to say this agreement in abstract. This concept(or result) have created a agreement between entropy generation and first law efficiency variation.

Now, What do I do?

7. ## Re: specific concept

Hi,

I want to write following these two sentences.

1.As a result, first law efficiency of thermodynamics variation is dependent to the entropy generation.

2.The point of minimum entropy generation coincides with the point of maximum first law efficiency of thermodynamics.

Now, I had a question. What good preposition can be linked to these two sentences?

Thanks
Best,
Ali

You have changed the name of the law to 'first law efficiency of thermodynamics?

not a teacher

Hi sir,

The law first efficiency Differs with first law efficiency. Law first is a definition.

Each device had a first law efficiency. In fact, here, first law efficiency is a Energy conversion efficiency.
