Para una producción de 520 MW se cuenta con la siguiente información:
* Flujo en peso de Gas Natural 19.35 kg/s

I would give more context, but I don't have any. Thanks for the help.

Discussion

Casey Butterfield (asker) Aug 17, 2008:
Mass v. weight discussion Since the original document uses peso, and not mass, it is my opinion that a true translation would have to adhere to the original faulty use of weight in the document.

My first instinct would be to call it mass, because I agree with José on his reasoning, but wouldn't the Spanish be masa if that's what was meant?
Juan L Lozano Aug 17, 2008:
Mass and weight I disagree with infinitus, of course there is a weight flow expressed in lb/hr; besides, weight is the mass of a substance or material multiplied by the acceleration of gravity (32.2 ft/sec2) in the earth. The mass of any substance is the same regardless of its location (the moon, the earth, Jupiter, etc.) Its weight is different, because it is affected by the force of gravity in such location.

Hi again

As I said I didn't do physics. But linguistically (and it seems in physics, too) there is a difference between weight and mass:

Types of Forces
Many students of physics confuse weight with mass. The mass of an object refers to the amount of matter that is contained by the object; the weight of an ...

and linguistically, in Spanish, both "peso" and "masa" exist. So I doubt they mean exactly the same thing.

agree slothm : Quite correct, mass and weight do not have the same units.

Well I never! Thank you! and the references on google!
agree José J. Martínez : You apparently did not take physics. Mass is what we call weight out of habit.
46 mins
No I did not take physics :-) Just biology...!
agree Francesca Samuel

Thank you!
disagree infinitus : weight flow just doesnt sound right in english. Also in English mass & weight are completely different in definition. Mass is simply the space and contents of an object. weight is heaviness. for example a ballon has more mass than a small chuck of marble.

The trouble is the NASA site has "corrected weight flow", so surely it must be acceptable and correct English?
agree Juan L Lozano : I totally agree

4 KudoZ points awarded for this answer. Comment: "Thanks to all for the lively discussion. Mr. Martinez is right about the science, but I agree with liz askew that the linguistics argument is too compelling not to use weight."

mass flow

many call mass as weight....the unit they are giving is kg per second that is weight per second but even mor correct is mass flow in kg per second

I want to mention that mass and weight have the same meaning. If it is a lay translation, the words are interchangeable but if one wants to be 100% correct, the term to use is mass. Since they used weight...that is what could fit but I do not think that they stop and weigh every second, so it should be mass to be physically correct, since we are talking about a flow. Mass is if we can relate it to a density, weight when we refer it to a scale on earth.
Note from asker:
I agree with you on the mass correction, but when the original document uses peso instead of masa I am inclined to go with weight.

Thanks Francesca. I am putting an explanation for my reasoning above. It is up to the translatir to use whatever word he or she wants, but they should look at the technological level of the document. What if it is highly tech and they put weight?
neutral liz askew : I have noted your comment José; others need to comment too in support of your contribution. I have laid my cards on the table:-) Buenas tardes!

disagree Juan L Lozano : mass flow and weitgh flow are different. What is expressed as kg/time (either hour, second, minute) is the weight of a substance flowing per unit time.
