What are /r/thermodynamics' favorite Products & Services?

From 3.5 billion Reddit comments

Hi ,

We have developed a community-driven app that allows creating shorts ( 30 seconds read ) on different categories of topics. This is based on a free app and there are no ads or cost involved as it's in beta
The idea is to have concepts explained in simple 30-second read content with linking to related shorts and also creating a series. You can swipe through the shorts as you would do in a social media app and deep dive or freeze an interesting subject to see content on that.
We have added more content on thermodynamics and fluid mechanics

You could download the app from

It's in BETA and has limited content as of now. We will be adding more based on the feedback.

I realise this is a bit late, but this weekend I will update my DroidProp app to handle superheated water as well. Check it out. Might be what you want.

Very nice website!

>Entropy seems tricky to define. Does my explanation work?

For the rotor to turn spontaneously, entropy has to increase in this isolated system, so the demonstration is correct. However, I would use it instead to demonstrate how pressure and temperature work (e.g., you could add sliders to introduce inelastic collisions that will simulate cooling). To demonstrate entropy specifically I would use a mixing process. Start with blue particles on one side and red particles on the other side. Open the barrier, and plot the concentration of each colour in each of the compartments over time.

P.S. I don't know how easy it is to use the js physics engine. If it's laborious, you might want to take a look at http://www.algodoo.com It's very easy to prototype demos in that simulator.

Can pressure be so great that water behaves like it is in low pressure? I used the equation you mentioned to figure out the boiling points of water on other planets. I was curious about a neutron star, found the surface pressure (2.4*10^29 mmHG) and plugged it into my formula and got -102 Kelvin (-375 C). I used an online conversion to double check and got -102.7 K.

Below is a link to a conversion tool with the values already inputted.

If you don't mind, could you tell me if this is actually possible (theoretically of course)

Im not sure which aspect u are looking but Combined Cycle Gas&Steam Turbine power plants from Kehlhhofer is one of the best book from technical point of view. We had used it in graduate level course. I strongly recommend

What properties are you looking for, specifically?

If it's heat transfer properties you're looking for, they are well documented in any basic heat transfer text - Incropera, Bergman et al (here) is a good one.
