Homework Statement
A hot wire is placed in a region of mass air flow. There is a current on the wire causing it (wire) to heat up. The current is regulated such that the wire temperature is constant.
Measurement of current on the wire is related to the mass airflow by King's Equation.
The goal is to perform a least-squares solution of measured data in order to determine coefficients of Kings equation.
Homework Equations
King's Equation: output = a + b * flow ^c
with a, b, and c coefficients to be determined.
The Attempt at a Solution
Solve equation using linear least-squares. Problem is the flow raised to the "c" coefficient. Linearization of the equation *may* be the answer? Otherwise using something like Levenberg-Marquardt's non-linear method?
