Which of the following is an advantage of Venturi cooling towers?

Venturi cooling towers are designed to effectively utilize the Bernoulli principle to enhance air movement through the cooling medium. The correct advantage of quiet operation indicates that these cooling towers typically do not require large, loud fans to operate; instead, they capitalize on the natural airflow produced by the design of the tower itself. This can result in reduced noise levels, which is particularly beneficial in environments where noise pollution needs to be minimized.

The other characteristics associated with Venturi cooling towers do not align with their advantages. For instance, requiring continuous maintenance, needing a large fan, and having high operational costs are aspects that could detract from the overall efficiency and practicality of this cooling tower type. Thus, the design and operational mechanism of Venturi cooling towers inherently promote quieter functioning as they harness natural airflow rather than relying on mechanical means that may generate significant noise.
