Input(s)

$x$: Brinell Hardness of Casing of Interest (dimensionless)

$d_{r}$: Entrance Hole Diameter in Reference Casing (in.)

$x_{r}$: Brinell Hardness of Reference Casing (dimensionless)

Output(s)

d: Entrance Hole Diameter in Casing of Interest (in.)

Formula(s)

$$ d=\left(\frac{\left[2,250+4.2 x_{r}\right]}{[2,250+4.2 x]}\right)^{0.5} d_{r} $$
