Sorry for the delayed response, Chester (Dr. Miller?). There's a lot to unpack here and I've been pulled between a dozen different things, all of them annoying. I've been trying to chip away at this a little at a time, so let me try to address your points one by one. This makes sense...

I got it working! I realized later on that by removing some mass from the system, I was effectively forcing a change of the specific volume. All I had to do was calculate the new specific volume, and assuming constant entropy, I derived a relationship between those properties and temperature by...

Thank you for the clarification! Right. And this is something I'll have to figure out how to work around if I end up needing to include heat transfer--which will probably be necessary if I want to validate my model with my experimental setup. I agree. Start simple. This is extraordinarily...

I thought the very definition of "isentropic" assumed the gas behaved ideally. Then again, I'm still trying to work out how exactly that would affect me if all I'm doing is tracking entropy on a saturated gas table. Speaking of which... Am I interpreting the isentropic process correctly? I...

Thanks for the insight, Chester. That's interesting--I hadn't really considered looking at it from an entropy point of view. One point I'd like to have clarified, though: How valid is it to treat this as an isentropic process? I would imagine that CO2 that's near-supercritical would diverge...

Hi PF! I have a tricky problem that I'm trying to model, and none of the typical textbook examples cover this--or they only cover it tangentially--so I was hoping to get some insight here. (Couldn't find a "Thermodynamics" section of the forums so if there's a better place to post this, please...

Yeah I have to agree. The appeal of naming things will wear out shortly. I'd like to see something a little more coop-based. What about building a corporate empire? Establishing colonies? Building bases for your ilk? Lots of open-ended possibilities.

Damn. I clicked that link thinking I would find the answer to what I want to do for my master's thesis :|

Hello! I'm also a Mech E, though I can't say I know much about energy waves, etc, beyond the basic physics courses. An EE with an advanced degree in plasma dynamics or whatnot might be able to be of some help...or just a regular physicist. Personally, I think the Halo energy sword is in the...

Funny, I came here to talk about the same thing, haha. I'm excited to see how NMS pulls it off. As I understand, the game is supposed to be more...exploration-based? I like how dense they make the universe seem with all the trees, animal life and whatnot, but it's not very realistic in terms of...

Hi PF! I'm a long time lurker - only posted a few times in the past. I love this place, and I think there's a lot of like-minded people on here who might (hopefully) find this interesting. I don't mean to be brigading or anything - just wondering if anyone is as excited as I am about this! Some...

That doesn't make sense. Why do I need to know the static friction if the sled is in motion?

Hi, I am having some major difficulties with this problem: A sledge loaded with bricks has a total mass of 18.5 kg and is pulled at constant speed by a rope inclined at 20.2° above the horizontal. The sledge moves a distance of 20.9 m on a horizontal surface. The coefficient of kinetic...
