## Homework Statement

Just a quick question. This is fairly terrible that I'm blanking on something as fundamental as this. It's to do with units and dimensions. So, Area, for example, = L * L = L^2. If I have a quantity, R, for example and let's say it's units are L. If I use R in some arbitrary equation and square it does it then become the |R|^2 L or |R|^2 L^2 (where |R| is the scalar component of R)???

## Homework Equations

The following is what got me confused about this. u(the average velocity) = 14/R

^{2}* u

_{max}(The max velocity) * (R

^{(1/4)}- R

^{(1/15)}.

## The Attempt at a Solution

So, the units don't check out in the above equation for velocity, do they?
