comment Cooling of a surface due to fluid passing over it
Please add a figure that contains all the variables that you defined. It will greatly help people to understand what you are talking about, I get lost in all your definitions of axis, sizes, et cetera.

comment How much money can I save on gas by losing weight?
Not really. I guess all terma involving the mass that may play a role are linear in the mass (roll friction, accelation power), so it is all included

@RobertStiffler Sure, I think the average velocity is a good way to tell that.

@pentane That is exactly why I am giving a range of 0-1.6%. There is no way to tell exactly

@Aequitas Ok, that is depends on the average value does not mean that I can give you a more exact value.

comment Numerically solving a simple Schrodinger equation with fast Fourier transforms
I think it is very well known in most subfields of numerical physics that FFT solvers are extremely efficient in solving a subset of all problem. Periodic boundary conditions are important (or as Daniel mentions, no "real boundaries" anyhow).

comment Momentum of slowly spinning (viscous) fluid
What is the difference between the $v_\theta$ with a dot and with the prime in your notation? Derivative wrt to $t$ and to $r$?
