Draw a free body diagram, and solve the problem as you see the forces there (gravity, upward acceleration included). The acceleration would be modified.
Try using a positive value for g. Since when you ultimately calculate time, using a negative value would result in a negative value under the square root.
Edit: Strike out what I said.
In 6 km, the change in pressure is significant.
Here's something to get you started:
Use the equation,
B=dP/(d(rho)/rho)
Manipulate and integrate,
integral of (d(rho)/rho) = integral of (dP/B)
That results in,
ln(rho2/rho1)=exp((P2-P1)/B)
Where you can say state 1 is the surface, and...
That is a bad question. There are various forms of energy in that given situation. Both A and C are correct.
There's heat transfer going on between the body and the ambient environment. However, there's electrical energy, kinetic energy, and chemical energy involved, as well.

Thanks, but that's not what I'm looking for.
I need to take the derivative of density with respect to y, and I need to use the shear stress to take the derivative. So I need to find a relationship between density and stress.
I've tried using the Newtonian definition suggested by Stokes. I...
Homework Statement
I have an empirically-derived equation for the shear stress of a fluid on a surface, given by the equation below.
I am supposed to take the derivative of density with respect to distance, and I must use this equation to find an expression for density.
Delta = Boundary...
EDIT:I realize the images are big. I'm the process of scaling them down and re-uploading them.
EDIT 2: Re-hosted and included updated images.
I apologize for the bump, but can somebody please just go through this formulation and verify my work?
It seems I am in fact eventually getting...
Does the total density relation to the partial densities look correct?
Intuitively, I was thinking total rho = rho_a + rho_v, but the equation, obviously doesn't support that.
Homework Statement
I am trying to integrate the momentum equation in the Navier-Stokes equations, and I need to make sure I have the density formulation correct. I'm unsure of my work because a lot of the terms in the end are canceling out.
It's a two-phase mixture, so the sum of the partial...
