Derivation of the Nonnalized Transfer Function

Using this equation it can be easily calculated what the change in boiling point is of water at 100 °C and 1015 mbar  

When the air pressure at sea level changes with 35 mbar, which is not uncommon, the boiling point changes by approximately 1 K. 

In the operating point we may write that Fm = Fouio = Fq. The mass balance can then be normalized to  

The time constant f is the residence time in the tank in the steady-state situation. 

Define the time constant for the total heating time ta
