Thank you so much,, i do understand it much better now..

I mean the physical meaning of the terms?

Trust mé. I have made a lot of searching. I know it tells about the behavoir of a fluid. But what is it used for ? To find acceleration or velocity of a fluid or? For my own understanding, it Will help mé to know, what the terms are in the equation. Maybe someone Can explain it to mé?

Hi guys. Can somebody give mé examples for what the navier stokes equation normally are uset for.? I do not understand or Can see, what we use it for.? And Can someone help mé understand the equation? Like what each term is?

Hi Again Guys. Maybe you can correct me in this: We are interessted in rates of change of K (velocity of acc) Material Derivative: D(K)/Dt. Tells us how K changes as time changes AND how K changes as it moves through space. (Similar to Langrian Description) partial time...

Maybe someone can explain me the difference between material and total derivative ? Isnt it the same?

Hi again. Yes I have read a a couple of books, and tryed to search the net? I only get this out of it: 1) ∂/∂t 2) D/Dt 3) d/dt And I read that total derivative and material derivative is "the same thing" ? I really hope some of you can help me a bit.

Hi Guys. I hope some of you are able to help me out. This is NOT a homework. I have to explain the difference between the three different rate of change (time derivatives) of a property (such as mass, momentum, internal energy, etc) in a continuum? 1 )The partial time derivative 2)...
