A counter flow cooling tower cools 2000 gal/min water from 104 F to 85 F with 210,000 ft^3/min of air at 90 F Dry bulb Temperature and 76 F WBT . The Mass transfer coefficient -surface area product is hA= 123lbm/hr ft^3. Air mass flow rate per unit cross sectional area of the cooling tower is [(mdot)a /A ]=1800 lbm/hr ft^2. Determine the volume and height of the cooling tower, effectiveness and relative humidity.
