Hi guys,
I keep getting an error on a formula, but the formula is just from one of my textbooks, so there isn't much I can change.
I am wondering why mathcad keep giving me this error.

Solved! Go to Solution.
The units are inconsistent in the equation. It's physically impossible to add Length^-0.5, Length^-1, and Length^-2.
Your equation is likely empirical where L.tot is expected to be a certain unit. Assuming that L.tot is expected to be in meters, and a.0 is supposed to be unitless, you can modify the equation like this:
which can also be re-written as:
If a.0 is expected to have units, just multiply the whole equation by those units.
