I used that book for thermo 2, and I hated it. Try using Wark's or Cengel's. If you want a more theoretical approach, you can go for Callen's "Thermodynamics and an introduction to thermostatistics"
yes, actually, I was trying to take the curl of the Navier-Stokes equation, to get the vorticity equation, a problem in Bird's transport phenomena, the book asks you to deduce it in two forms, the first one is the one I have already, the second one involves the Levi-Civita symbol and I'm...
I know now, thank you. Actually that "identity" es not true unless Div(v)=0, because another term is missing. However that fits perfectly since I am working with fluid mechanics.
Thanks again!
I finally found it, looks like I was missing another term in the right side v(Div(v)), altough this is 0 in my case because I am working with fluid dynamics. Now everything makes perfect sense, thanks anyway
is this identity true?
V is a vector, so VV is a second order tensor
I have tried to prove this but the components of the tensor appear always as operands of the nabla.
Thanks!
Div(VV)=v.(Grad(V))
Homework Statement
I just want to check if this identity is true, since I have not found it anywhere, can anyone help me?
v is a vector (and that nu is supposed to be a v too)
Yes, actually I want to do the molecule attached, as you can see, it is not an activated system, that's why I thought I could use aromatic nucleophilic substitution
Hi!
Im a student in chemical engineering and I would like some recommendation for a fluid mechanics book, I've been using Bird's Transport Phenomena but it seems to be a bit difficult to follow it, as it skips a lot of steps.
Does anyone know if an aldehyde, specifically, acetaldehyde behaves as a good nucleophile? I'm trying to insert an aldehyde in an aromatic compound through an aromatic nucleophilic substitution, any information or source to pKa data would also be appreciated, thanks!
Homework Statement
I've been asked to explain how would I synthesize an organic compound, its structure is attached as an image (first attachment) , could you help me figure it out? I'm supposed to start from benzene
The Attempt at a Solution
So far, I've got a big part of the...
well, the problem is that my equation is not so simple, it is actually a pretty big fluid dynamics model for calculating the viscosity of a mixture of 10 gases, so I have an equation, lots of constant properties, and I am trying to get a 10x10 matrix :S
Just an urgent doubt, I am new to matlab.
So imagine an equation that has two indexes, and that can be expressed as a matrix, how can I do something like this in Matlab? using a for cycle?
