I'd love to confirm what you have, however, for some reason the attachment is "pending approval." I can't view it. Left boundary is a vertical line at x=0. Right and bottom boundary is y=e^x. Top boundary is y=pi. There's an intersection point where y=e^x and y=pi meet. It should look like a...

Either I'm very tired and can't think, or this solution has a serious problem with negative signes everywhere. A ratio of a/b=0.8 was picked just as an example for a gap. Using r/b is just a better choice when it comes to interpreting results. When the ratio is 0.8, you're at the inner...

I'm having problem understanding this one, can clarify and help answer? A material region is defined as one where the surface velocity W is everywhere equal to the fluid velocity V. Such a region always contains the same fluid. Is it possible to define W in a less restrictive way and still...

I'm having trouble with the 2nd part of this problem. By letter "d" I mean "partial," I wasn't able to preview latex, so I went without it. x=x'+V*t' (V is a constant) t=t' f=f(x,t) Part a ===== Find df/dt' and df/dx'. I got the following: df/dt'=df/dt+V*(df/dx) df/dx'=df/dx...

Yeah, that's what I ended up doing.

Hi, I need help solving this problem. On one hand, I think that there's not enough information to solve it, on the other hand, I think there has to be a way to cancel out all the information that's not provided, and do the problem with only what's given. But I can't come up with a way to solve...
