You turn to the chapter "Drift Eliminators." The cross-section diagram shows that drift eliminators (chevron-shaped) collect water droplets. If they are coated with algae, the velocity pressure increases.
: As air moves across these droplets, a small portion of the water evaporates. This phase change from liquid to gas absorbs a significant amount of heat from the remaining water—roughly 1,050 BTUs for every pound of water evaporated. The Result cooling towers principles and practice pdf
This real-world outcome demonstrates why mastering both the principles (psychrometrics, approach, wet-bulb) and practice (inspection, maintenance, adjustment) is indispensable. You turn to the chapter "Drift Eliminators
The cooling limit is governed by the wet-bulb temperature of the ambient air. Key Components This phase change from liquid to gas absorbs
The primary cooling mechanism is the evaporation of a small portion of the recirculated water. This process removes the "latent heat of vaporization"—approximately 1,050 BTUs for every pound of water evaporated.
