Volume of rock dissolved per unit volume of acid (acidizing)

Input(s)

ρ15 percent HCl\rho_{15 \text { percent } \mathrm{HCl}}: Density of 15 Weight percent HCl\mathrm{HCl} Solution, (g/cc)(\mathrm{g} / \mathrm{cc})

ρCaCO3\rho_{\mathrm{CaCO}_{3}} : Density of Calcium Carbonate (g/cc)(\mathrm{g} / \mathrm{cc})

β15 percent HCl\beta_{15 \text { percent } \mathrm{HCl}} : Mass of Dissolved Rock with 15 percent of HCl(g/g)\mathrm{HCl}(\mathrm{g} / \mathrm{g})

Output(s)

X15X_{15}: Acid Dissolving Power (cc/cc)(\mathrm{cc} / \mathrm{cc})

Formula(s)

X15=ρ15 percent HCl×β15 percent HClρCaCO3X_{15}=\frac{\rho_{15 \text { percent } \mathrm{HCl}} \times \beta_{15 \text { percent } \mathrm{HCl}}}{\rho_{\mathrm{CaCO}_{3}}}
