I have a question, I am getting ideas for possible thesis research, this may be hair-brained but hear me out. I have been looking around for a little but maby someone knows, has anyone done research on fluid flow and water distirbution in zero or near zero gravity? I am guessing that this is basically the same as hear with earth's gravity, but wouldn't bernoulli's equation breakdown somewhat. Since the V^2/2g value would then be dividing by zero which is erronious.
sorry hit wrong button sorry hit the submit button a little too early anyway would there be a way of having a variable gravity term rather than 9.81 m/s^2 which we use. is there such a thing as variable gravity term anywhere at all. The idea I had was the closer to earth the more earth's graity 'pulls' on you. Well I obviously have more thinking to do, any ideas?
Not sure about this, but I think that many fluid equations like the Bernouilli equation have already been derived from more fundamental equations such as Navier-Stokes. I suppose that instead of putting in a potential like v(r) = mgr (for objects near the earth), and using something along the lines of V(r) = K<sub>G</sub> m<sub>earth</sub>*m / r would yield better results. But I should warn you that I am not familiar with the derivation, or the Navier-Stokes equation for that matter Please Register or Log in to view the hidden image!... But perhaps it gives you something for a starter to look at (a possible derivation and how gravity is implemented there). Bye! Crisp
thanx I am looking at the derivation and breakdown of the Bernoulli and will start looking at the derivation of the N-S equation and it's relation to the Bernoulli. Good idea
The universal Gravity constant might be what you speak of. http://csep10.phys.utk.edu/astr161/lect/history/newtongrav.html check there to read up on it.
gravitational const? Thanx for the information and the link I am going through it now, but just one thought. I thought that the idea of a gravitational constatnt was or could soon be of sorts debunked. I think maby Hawkins or some other article or book I read may have said this, do you know anything about this?
