Then the capacity $ is

and after calculations,

The cooling tower functioning in an air cooling situation is illustrated in Fig. 4.21.
Because of the logarithmic enthalpy difference the solution must be iterated:

When the cooling tower was operating as a heat recovery device, its ca
pacity was considerably higher because of the high temperatures and humidi
ties. In case (a) we had

in other words, the water spray turns in the direction of the air flow.
