Governing equations

The exact equations the solver works for a cooling tower — the same math shown in the app's "Theory" panel, not a black box.

Q_{rej} = F\,(h_{hot} - h_{cold})

\dot m_{evap} = Q_{rej}/\lambda,\quad \dot m_{blowdown} = \dot m_{evap}/(N_{cyc}-1)

\dot m_{makeup} = \dot m_{evap} + \dot m_{blowdown}

Q_{rej}: heat rejected to ambient [W]
F: circulating-water flow [mol/s]
h_{hot}: hot-water enthalpy [J/mol]
h_{cold}: cold-water enthalpy [J/mol]
\dot m_{evap}: evaporation loss [mol/s]
\lambda: latent heat of vaporization
\dot m_{blowdown}: blowdown loss [mol/s]
N_{cyc}: cycles of concentration [-]
\dot m_{makeup}: makeup water = evaporation + blowdown [mol/s]

Parameters

outlet_temperature [K, required, < inlet]; optional latent_heat [J/mol, default 40700] and cycles_of_concentration [-, default 4]. Reports heat_rejected, evaporation_rate, makeup_rate. Opt-in Merkel/NTU sizing: wet_bulb_temperature [K] + l_over_g [-] add the tower characteristic KaV/L, approach, and range
