[Grammar] is or are

[ali_dd]

Hi,

Is use of "is" in the following sentence correct grammatically and conceptually? If it is not, kindly suggest ways to make it clearer.


In present work, proposed design (variable thickness blade) has a higher efficiency than the original design (constant thickness blade) at the high flow coefficient (ϕ=0.275). By using such a Wells turbine, the cleaner air in the environment will be created because the amount of fossil fuels consumption and air pollution is decreased more at the high flow coefficient in order to produce the electrical energy.

The subject of "is" is "amount", which is singular. Therefore is is correct. However, the sentence is best cast aside and rewritten along the lines RobertJ suggests.

Why don't you consider this:

"Our analysis shows that the proposed design, i.e. a variable thickness blade, has a higher efficiency at a high flow rate (phi = 0.275) than the original design which used constant thickness blades. By using such a Wells turbine, cleaner air will result because the decrease in the amount of fossil fuels consumed will contribute to an overall reduction in pollution. A relatively high flow coefficient will produce the same amount of electrical energy and also benefit the environment."

And by the way, "is" in your post should be "are". Also, sorry, but it is not well-written.

Thanks.

What is your exact meaning of "same"?

Thanks.

Same means similar. Here using the variable thickness blade produces a similar amount of electrical energy when compared to constant thickness blades.
