Exception for Henrywood and Agarwal, Equation (3)

Math

\[c0 \cdot \sqrt{\frac{A}{V \cdot \ell}}\]

C

double f(double c0, double A, double V, double l) {
        double r9916003 = c0;
        double r9916004 = A;
        double r9916005 = V;
        double r9916006 = l;
        double r9916007 = r9916005 * r9916006;
        double r9916008 = r9916004 / r9916007;
        double r9916009 = sqrt(r9916008);
        double r9916010 = r9916003 * r9916009;
