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 r8406 = c0;
        double r8407 = A;
        double r8408 = V;
        double r8409 = l;
        double r8410 = r8408 * r8409;
        double r8411 = r8407 / r8410;
        double r8412 = sqrt(r8411);
        double r8413 = r8406 * r8412;
        return r8413;
