Assignment:
A cooling tower, 2 m in diameter, packed with 75-mm ceramic Hiflow rings, is fed with water at 316 K at a rate of 25 kg/m2-s. The water is contacted with air, at 300 K and 101.3 kPa essentially dry, drawn upward countercurrently to the water flow. Neglecting evaporation of the water and changes in the air temperature, estimate the volumetric rate of airflow, in m3/s. which would flood the tower.
Provide complete and step by step solution for the question and show calculations and use formulas.
