Validation model for mixing volume with adiabatic cooling

Information
This model validates the use of the mixing volume with adiabatic cooling.
Water in liquid form at room temperature is added to the volume,
which decreases its temperature.
The instance volSim uses a simplified implementation of the
mass balance that ignores the mass of the water added to the volume,
whereas the instance volExa uses the exact formulation.
The output of the instance relErr
shows that the relative error on the temperature difference between these
two options is less than 0.1%.
