It's... It's so beautiful
3. ## New Horizons

Seems the "phone home" signal has passed Saturn's orbit. Can't be long now!
4. ## New Horizons

What's the ping?
5. ## Who will solve this first ?

Yea fair enough. So if you change the variables in this task you magically get different nozzle sizes? Is that where my common sense went astray?
6. ## Who will solve this first ?

What if I make the nozzle smaller? So I can only get 250l/s through it but the pump still applies 1 MW?
7. ## Who will solve this first ?

I imagine it is significantly less than 1 MW?
8. ## Who will solve this first ?

.5 m/s for a 1mÃ‚Â² nozzle. That's where my confusion started:)

why not?
10. ## Who will solve this first ?

Thank you for explaining that. It makes sense. And it answers why both, the flow rate and the power are described in the task. But is it realistic? As I illustrated above, pumping 500l/s through a 1mÃ‚Â² pipe will not get us anywhere near a 200m fountain, independent of the power at hand. I think that confused me. If I were to just write down "Since we're pumping water, it depends on the nozzle"... would that be wrong? (I see it's not the desired answer, but isn't that true?)
11. ## Who will solve this first ?

No. (charlimit makes me post this, too.)
12. ## Who will solve this first ?

I guess I'm nitpicking here. The question "What height does the water reach" should be "what maximum height can the water reach". If that is the actual question then there is no point in mentioning the 500l/s If I force 500l/s through an infinitely small hole i theoretically get infinite speed. If I don't have infinite power, I obviously can not do that (the power at hand is stated). So what is the 500l/s mention for? is that a distraction?
13. ## Who will solve this first ?

Thanks for pointing out where in the text i can find it as a reply to my question about why it is mentioned at all. I still don't understand why, seems I suck at physics.
14. ## Who will solve this first ?

I asked why, not where
15. ## Who will solve this first ?

Passing .5mÃ‚Â³ through a 1mÃ‚Â² opening in 1 second gives me a flow speed of .5m/s. The 200m height is not specified in the question, neither is the nozzle size. - - - Updated - - - Yea but why is the 500l/s specified in the question?
16. ## Who will solve this first ?

If the nozzle is a 1x1x1 m cube and I pump 500l/s through it I get a velocity of 0.5 m/s. I somehow don't see that getting up to 200m.
17. ## Another live stream of a rocket launch!

ESA live coverage just started http://www.esa.int/Our_Activities/Navigation/The_future_-_Galileo/Launching_Galileo/Watch_Galileo_launch - - - Updated - - - T minus 10 minutes
18. ## Dawn at Ceres Thread

WP states that the entire project was cancelled numerous times, So maybe the tech on board is just a bit old. Also consider that 1 MPixel doesn't even sound so bad regarding that Hubble had just 2.56 MP. This is what the cameras look like btw: (notice all the space tape)
19. ## [Computers] Overclocking

Funfact: Maxmaps runs an OCd machine
20. ## [Computers] Overclocking

My good ol' Core 2 Duo is running on 2.8 (1.86 original) since 2007. Guess I would have bought a new one years ago without the OC boost. So, yea, good investment I'd say
21. ## What did you do in KSP today?

Got this contract to send a probe to do amospheric scans on Laythe in some specific spot. Landed the craft because parachute. Admired the sunset (or sunrise?) Panned the camera to the left awesome
22. ## Squadcast Summary (2015-02-07) - The 'Not Very Interesting' Edition

Max is not very talented in inclination matters
23. ## I am saddened by this but, I'm getting bored.

Yes. Took a ~1 year break, started playing again and the game was fun again like when I started. There's something weird about KSP that makes me overplay it until I'm bored or frustrated or something.
24. ## ATV-1 Deadly Reentry

Too spectacular to not just leave this here
25. ## Ion Engine Renamed by Ted.

Most people who have tried it call it "Yawn"
