Rules of Thumb
Cooling Towers
  1. Relative cooling tower size is sensitive to the difference between the exit and wet bulb temperatures (see the table):

    Temperature Differential F5 1525
    Relative Volume2.4 1.00.55
  2. In commercial units, 90% saturation of the air is feasible.
  3. Tower fill has a highly open structure to minimise pressure drop, which, typically, is a maximum of 2 in. in H2O.
  4. Water in contact with air under adiabatic conditions eventually cools to the wet-bulb temperature.
