Homework Statement
Hi all, this isn't exactly a homework question (I'm a law student long out of high school maths!) but has arisen in the context of some of my legal work analysing the difference in height of windspeeds re: wind turbines.
The "problem" is solve for the constant z0.
Homework Equations
The main formula is as follows:
vh = vref . (h/href)^(1/(ln(h/z0)), where vh = velocity at desired height, vref = velocity at measured height, h = desired height, href = measured height, z0 = aerodynamic roughness.
After inserting a known answer from a previous calculation, the formula reduces to:
(6.4/4.56) = 13.125^(1/(ln(105/z0))
The Attempt at a Solution
As I stated earlier, I'm a couple of years out of high school maths and cannot remember for the life of me how to solve for powers involving logs themselves. I can barely remember the simplest of log rules.
Any help would be much appreciated.
Many thanks all,
AA
