Pretty close. Except we didn’t have a black guy.

That's not the mass of the fuel, it's the mass of the rocket with fuel. And neither one is a rate. They are masses before and after the burn.So the rocket equation tells us that our available Delta V is proportional to the velocity of the exhaust and the natural log of the initial mass of fuel divided by essentially mass flow rate.
The Newspeak EncyclopediaI've talked about this before, but separate from "censorship" (maybe call it a different form of censorship) is that if I look something up on Wiki on my laptop in America in English, and tell a friend in say Russia to do the same on his laptop in Russian, there are often very, very different accounts of history, and I don't mean due to translation issues, I mean completely different content.

We have a saying in the rocket business. If the fuel don't flow, the rocket don't go.That's not the mass of the fuel, it's the mass of the rocket with fuel. And neither one is a rate. They are masses before and after the burn.

You should stop pretending you know what you're talking about. Your edit was wrong too and has since been corrected.Like I said, "essentially". So calm your 8th grade math tits. Sorry, it was 3 years ago, not sure what my point was. But, to know your final mass you'll need to know the time of the burn and the mass flow rate because when you are actually using the equations you are generally targeting a dV and want to know your burn time. Or you want to know how much fuel is left and velocity after a burn of a certain duration.
I mean this sincerely. Go F u c k yourself, moron.You should stop pretending you know what you're talking about. Your edit was wrong too and has since been corrected.
"But NTR’s easily achieve 800 ISP and possibly up to 1200 ISP.ANd real engines were tested and built back in the 50's. "
Ha! You wish.
Maybe you should reintroduce your error into the derivation on Wikipedia and see how long it takes someone to fix it.I mean this sincerely. Go F u c k yourself, moron.
Are we upset, and cussing, over rockets? Because if so, I need to know. For me, I just push em around the air in my livingroom and make the engine noise with the back of my throat.Okay the 60's. You can go f u c k yourself too.NERVA - Wikipedia

Sigh....you can't just make a 'back of your throat' reference without also including a mom joke. Even your mom knows that!Are we upset, and cussing, over rockets? Because if so, I need to know.

Stay calm and rocket on.

That'll do, auggie... That'll do.Noted.
@ThreatMatrix I want to amend my previous comment. When I'm sitting criss-cross Indian style, I'm in your Mom's living room and pushing the rocket through the air. That's when I make the rocket noise using the back of my throat.
@Back Alley Gator , how was that?
