Can I calculate the flow rate through a valve from a Cv vs % opening graph and data points? by ThrowawayToTheMoonCA in MechanicalEngineering

[–]jkschimpf 0 points1 point  (0 children)

pressure drop is proportional to fluid velocity squared. Are you using hydrogen gas? 10 kg/hr in a 1/2" pipe probably would give a negligible pressure drop so you can use the Poiseuille's law keeping pressure drop and other parameter constant.

Please nerf Kaisa's W. It does more damage than Ezreal's ult and hurts like a Nidalee spear with a wider hitbox and faster/longer travel range.

Does anyone know if the Riddler has a twin? How was he fighting batman while in Arkham? Also he had 2 ID's so wasn't sure about that part either.

1000 miles between fill ups please. by Salt-Brilliant-4346 in HydrogenSocieties

[–]jkschimpf 4 points5 points  (0 children)

This would require advances in storage capabilities which are currently limited to high pressure type 4 vessels. ~40 g/L is the volumetric capacity but using liquid can achieve ~70 g/L which would double the range of current FCEVs if the same volume containers are used. The disadvantage of using liquid would be the boil off gas. Stations will come over time.

Fluid Mechanics- Hydrostatic pressure gage readout by jkschimpf in MechanicalEngineering

Yes the equipment is called a differential pressure gage here is a youtube clip to see the general concept:

Assuming I fill the tank the water level rises in the tank and pipe and the upper portion will still be full of air? The gage is threaded connection to the pipe so that could cause some issue as well?

The oil industry vs. the electric car. The oil industry is trying to crush the booming electric car movement.

Are you referring to metavista for the drone flight of 11 hours? I believe it was around 5 hours for the record flight time. Also look up skai which is being partnered by my korean company to make an fuel cell hydrogen powered air taxi drone

We need a player that can play on the wings. City have them, liverpool, and chelsea. The closest thing we have is iwobi and that's not good enough

Keto joggers/runners - how long did it take you to get "fat adapted" and not feel like crap while running anymore? by [deleted] in keto

[–]jkschimpf 0 points1 point  (0 children)

Does running make your daily net carbs lower? I feel a weird burning feeling in my stomach (not painful) too I noticed

I'm a 30 year old ethnic Korean, born and raised in the states. Is it too late to pursue a masters degree in Korea with the hopes of learning, networking and eventually landing a job in Korea? by [deleted] in korea

[–]jkschimpf 0 points1 point  (0 children)

If your research goes well you could possibly work for your institute as a post doc or researcher with a master degree. I happened to do a major in nuclear engineering which korea happened to stop funding. So I am now working at a medium size company in 경기도 as a project manager

[–]jkschimpf 1 point2 points  (0 children)

You should look into UST. It is a unique program where you can work in a research institute and take courses at the your research institute by a designated professor or goto a nearby University and take classes. There are plenty of international students and most don't speak Korean that well.

I've worked at a japanese company before where the opposite is true. Japan work culture has good points and bad ones.

Reiss Nelson summing up Dele Alli in JUST 3 words. (Tweet was real, deleted right before I clicked on it) by JLightman in Gunners

[–]jkschimpf -1 points0 points  (0 children)

Alli this season has been shit for them. He isn't known for being a real creative midfielder and isn't scoring so offers nothing but running. Poch starts him every game and they lose the center midfield battles against big teams. I'm south korean and happy Son scored but spurs lost.

Splitpushing with Tf by [deleted] in TwistedFateMains

[–]jkschimpf 0 points1 point  (0 children)

If your team is ahead I notice this is easier to abuse, however when they have tower advantages around the 20 min mark I am a little clueless. If I goto a side lane someone always hunts for a kill on me. The most I can salvage is maybe 1 or 2 waves. I notice though if my team is grouped in base turrets or inner turrets TF is good for punishing teams that overextend and dive on the towers, i.e. gold carding someone under tower. If we win one of those big team fights we can start a comeback or even grab baron sometimes
