In water cooling tower air enters at a height of 1 m above the groundlevel and leaves at a height of 7 m. The inlet and outlet velocities are 20m/s and 30 m/s respectively. Water enters at a height of 8 m and leaves ata height of 0.8 m. The velocity of water at entry and exit are 3 m/s and 1m/s respectively. Water temperatures are 80°C and 50°C at the entry andexit respectively. Air temperatures are 30°C and 70°C at the entry andexit respectively. The cooling tower is well insulated and a fan of 2.25 kWdrives the air through the cooler. Find the amount of air per secondrequired for 1 kg/s of water flow.
