Heat ratio of contents in a geothermal reservoir

Input(s)

$\varnothing$: Porosity (dimensionless)

$\rho_{w}$: Water Density $\left(\mathrm{kg} / \mathrm{m}^{3}\right)$

$C_{w}$: Performance Coefficient, a Function of Mean Pressure Level $\left(\mathrm{KJ} / \mathrm{kg}{ }^{\circ} \mathrm{C}\right)$

Output(s)

$H_{w}$: Heat in Water Content $\left(\mathrm{KJ} / \mathrm{m}^{3}{ }^{\circ} \mathrm{C}\right)$

$H_{T}:$ Total Heat $\left(\mathrm{KJ} / \mathrm{m}^{3}{ }^{\circ} \mathrm{C}\right)$

Formula(s)

$$ \frac{\mathrm{H}_{\mathrm{w}}}{\mathrm{H}_{\mathrm{T}}}=\frac{\rho_{\mathrm{w}} \mathrm{C}_{\mathrm{w}} \varnothing}{\rho_{\mathrm{w}} \mathrm{C}_{\mathrm{w}} \varnothing+\rho_{\mathrm{r}} \mathrm{C}_{\mathrm{r}}(1-\varnothing)} $$
