Thank you! Nice to know about this tool, very useful, I used: http://www.chemistry.mcmaster.ca/~ayers/chem2PA3/labs/2PA36.pdf" Equation (14) My results are slightly different, but the process in question is not isothermal, isobaric, or isochoric, the constant is enthalpy since it...

Thanks for the reply, but I can't see how to find the Joule-Thomson coefficient.

For future reference, I did figure out that you can calculate the Joule-Thomson coefficient using Van der Waals constants. Another option uses Beattie-Bridgeman constants. So I was able to figure it out from those known values.

I've been scouring the web in search of a Joule Thomson coefficient value for methane, but so far no luck. I have the volume, temperature, and specific heat as well... so I could also use the coefficient of thermal expansion for methane.. but I can't find that anywhere either! Does anyone...

I think the difference is that I was assuming an isochoric process, since a tank of fixed volume held the process. Maybe this is not the case? Either way, it should be noted that in my case I am just looking for a valid approximation, so I do not wish to model a differential problem. I have been...

Consider a problem where a tank holds compressed natural gas, compressed to approx. 250 times atmospheric conditions. Now release the tank valve letting some of the gas out. Assuming a small timestep, I can approximate the energy lost as 1/2 mv^2, where m is the mass released during the...

Thanks for all the replies. I should note, to clear up confusion, I am not actually a teacher! Just an undergrad mechanical engineering student.

Does anyone know of a good science/engineering series, exploring a broad range of topics. Essentially I'm searching for Bill Nye for undergraduate/graduate students. thanks :)
