This formula uses 1 Functions, 2 Variables
Functions Used
log10 - The common logarithm, also known as the base-10 logarithm or the decimal logarithm, is a mathematical function that is the inverse of the exponential function., log10(Number)
Variables Used
Coefficient of Friction - The Coefficient of Friction (μ) is the ratio defining the force that resists the motion of one body in relation to another body in contact with it.
Winglet Reynolds Number - Winglet Reynolds number is based on a length, which is usually the chord length of an airfoil (in two dimensions) or the chord length of a winglet.
STEP 1: Convert Input(s) to Base Unit
Winglet Reynolds Number: 5000 --> No Conversion Required
