How about this one: Using the given equation solve for the friction factor(f) of a turbulent flowing liquid through a pipe. Diameter = .02m, roughness coeffecient(e) = .000015m, Reynold's number = 6.829*10^4.
Here's the equation:

All the numbers are given so all you have to solve is a single equation. Let me know what method you used and what units the answer is in.
Weird, mister 'Americans are bad at math' seems to have conveniently forgotten this thread.
