Specific Conversion Needed

What is the calorific value of the gas?

Do your own homework. There are lots of conversions sites on the internet.

Use the brain capacity that got you here to find one of them, then mark it so the next time you have a conversion problem, you'll have the cheat site handy.

There's about 35 kBTU in a cubic meter of natural gas (when burned), but what in the world is a Nm3/d? Is it a nano cubic meter per day or Newton cubic meter per day? Neither choice makes any sense to me. I presume the desired conversion unit, MMBtu/d is a million British Thermal Units per day. (I never understood why MBtu is a thousand British Thermal Units. There is no M in the English word thousand.)

Oh, about the numbers I and the OP have presented here. The OP presented five significant figures for a value for whatever unit that they have. I presented an easy to calculate in my head rounded off to only two digit number. If this is homework you must find the higher resolution number that I found or you will loose all of your precision. In other words, if you just multiply by 3.5E-3 you will get the wrong number for homework but it will be close enough for most purposes. The higher resolution number is out there, you just have to find it.

The M for a thousand probably comes from the Roman numeral. Some cooling tower manufacturers still use MBtu for 1000 Btu, but I agree with your preference for k.

Nm³:m³ :: scfm:cfm; i.e., nominal:standard.

You are correct "M" when used in the term MBtu is the Roman numeral for 1000. As "C" is 100 etc.

Seems we learned that in or about the 4-5 grade here, some 50 plus years ago. But we don't teach like we used to for some reason. Don't need to know all of that stuff anymore with these fancy computers. Just get onto this forum and someone will tell you what it is.

Hi redfred,

Nm3 stands for Normal Cubic Meter; Normal means that the gas is at 0ºC and 1 Atm. pressure.

It is similar to SCF.

The answer is 4,992,750 ft³/day. Can you do the rest?
