High pressure gases specific heat

AI Thread Summary
To calculate the reaction heat in an ammonia converter at 500°C and 200 bar, specific heat values are needed for nitrogen (N2), ammonia (NH3), argon (Ar), and methane (CH4). While specific heat data at 500°C is available, it is challenging to find corresponding values at the higher pressure of 200 bar. The NIST website was suggested as a resource, but it does not provide data for ammonia at that pressure. Specific heat values provided include: Nitrogen (Cv: 0.1977, Cp: 0.2738), Ammonia (Cv: 0.6080, Cp: 0.7906), Argon (Cv: 0.07550, Cp: 0.1314), and Methane (Cv: 0.8018, Cp: 0.

I want to calculate the reaction heat in a ammonia convertor but I need some
specific heats of N2,NH3,Ar and CH4 at 500°C and 200bar. I could find data at 500°C but not at that pressure.


thanks Stefaan

Hi Stefaan,
I was going to suggest the NIST website but I see they don't go up that high in pressure for ammonia at least.

Values below are in Btu/lbm-F.

Fluid / Cv / Cp
Nitrogen / .1977 / .2738
Ammonia / .6080 / .7906
Argon / .07550 / .1314
CH4 / .8018 / .9490
 

Thread 'How could I make it so ferrofluid drops do not coalesce?'

Hello! I've been brainstorming on how to prevent a lot of ferrofluid droplets that are in the same container. This is for an art idea that I have (I absolutely love it when science and art come together) where I want it to look like a murmuration of starlings. Here's a link of what they look like: How could I make this happen? The only way I can think of to achieve the desired effect is to have varying droplet sizes of ferrofluid suspended in a clear viscous liquid. Im hoping for the...

Thread 'How do you fabricate microfluidic chips in your lab?'

Hello everyone! I am curious to learn how laboratories handle in-house chip manufacturing using soft lithography for microfluidics research. In the lab where I worked, only the mask for lithography was made by an external company, whereas the mold and chip fabrication were carried out by us. The process of making PDMS chips required around 30 min–1 h of manual work between prepolymer casting, punching/cutting, and plasma bonding. However, the total time required to make them was around 4...
