A very interesting and clearly explained discussion about normal cubic meters! Great work Pat 👏

Hi Pat. Your videos are really helpful in getting me insights as a Process Engineer. Thanks a lot man. Expecting many more videos to come from you

Nice topic pat. Always nees to be extra careful with units while working with gases. In general we check with mass flow and operating conditions on datasheets to be safe.

Are you gonna continue with these videos? They are so cool and interesting and you explain the topics really well. It would be a shame if you don't continue bc there are not many chemical engineering channels that are this entertaining, interesting and informative

Hence why I'd almost always convert to mass or molar flow and convert to volume back whenever necessary

In Chemistry we used 273 kelvin (0 degrees Celsius) at 1.0 atm for STP. We also used 1.0 mole of gas had a volume of 22.4 liters at STP. This is what we used in PV = nRT to get the value of R. These are nice units to use because of the ease of remembering the ones for P and n, and 22.4 is also easy to remember.

Wow!!! Like you this has bothered me no end for the past few decades. Nm3 is Newton meter cubed. That's for sure. In our statute books it's also listed as Nm3. I agree that this parameter should be changed to Vol(n). After all, if there is a Nm3, would there be a Nm (Normal meter) or NW (Normal Watt) or Nkg? That's stupid!! And maddening!! Also many decades ago before the advent of internet I found out that standard temperature is 21.1 deg C. Can't remember where. But there there are different standards, 25, 20, 15, take your pick. Its mind bogging!!

Model this as an electrical circuit and the answers fall right out. This is because, as an electrical circuit, any difference in pressures (or voltages) between two points in a flow path DEMANDS that there be a resistance (or flow restriction) between the two points. If there is no difference in pressure (voltage) between two points an infinite flow (current) will result. Since this doesn't happen in real life you have to consider the pipe as having some resistance. And since it will not usually be enough resistance, an external resistance, or valve, needs to be added. If you need to drop 8 bar in the "B" flow then the valve could be replaced with a check device (spring and ball check valve that opens at 8 bar) that drops 8 bar across it when a fluid is flowing through it. This will of course release heat at the check valve or regulator. It also points out that you were really asking the wrong question to begin with. The right question was "How do I get the flows I want given the initial conditions."

Nice video! The discussion of average molecular weight makes things unnecessarily confusing in my view. Standard volumes are equivalent to molar quantities. The gases molecular weight is irrelevant.
@ishandave9584 Жыл бұрын
But why do we use Nm3/hr afterall. Why dont we just use kg/hr instead. Is there any application where Nm3/hr is better to use? Nm3/hr neither gives mass flow nor volume flow. It gives some imaginary volume flow that would have been there, the conditions been 1atm and 0degC.
