Interpolation for Fancher and Brown correlation

It will calculate the friction Factor by interpolating in the digitized plot produced by Fancher and Brown. The values provided for the interpolation are the \(D\rhoV\) product on the x-axis, the GLR and the degree of the poliynomial.

interp.fanbr(drhov, GLR, degree)

Arguments

drhov

Duns and Ros parameters. See equation on x-axis
GLR

gas liquid ratio
degree

degree of polynomial
