Thanks for your comment. Hopefully this page clarifies the video a bit more: www.bronkhorst.com/int/service-support-1/technologies/volume-flow-versus-mass-flow
@@BronkhorstFlow Take another look at the original video. At the two minute mark the discussion turns to what is normal and standard conditions for gas volume and flow rate. The speaker uses the term "mass" when it should be volume. It is no big deal but will cause confusion.
@@RickKempf Thanks for your respond, but the speaker did not make a mistake. He describes mass flow rate being expressed as e.g. ln/min being litres-with-suffix-n-per-minute. Suffix-n stands for normal conditions (pressure and temperature), which defines volume flow in such a way that it may be called mass flow.
@@woutvantwel587 When using the term mass flow rate, the units should be grams/minute, kilograms/hour, metric tons per day, etc. When describing volumetric flow rate of a gas, terms like normal liters per minute, standard liters per minute, standard meters cubed per hour are appropriate. I am not trying to be difficult but want to help you avoid a future stream of questions and comments on the point. Blessings to you all! Rick
@@RickKempfI am sorry, but you are missing the point of the video. What Bronkhorst describes is the fact that ln/min can be directly recalculated into g/min. Without the suffix n (l/min) it would be a volumetric flow expression. To convert l/min into ln/min you need an agreement on the temperature and pressure conditions, at which you perform that calculation. Please trust me, ln/min or SLM are accepted mass flow rate units. Feel free to check this on Wikipedia or other sources e.g. Websites of Bronkhorst’s competitors.
At the 2:00 mark, mass flow should be volume flow
