Cooling water flows in a tube bank that receives heat by convection. The velocity of the water is 0.24 m/s and the temperature of the water body is 10°C. Each tube has a diameter of 1 inch and a length of 3 m and is arranged in a staggered manner. In the longitudinal direction (in the direction of flow), the distance between 2 tubes is 2 inches with 6 rows. In the transverse direction (perpendicular to the flow), the distance between the tubes is 2 inches with 60 tubes. Inside the tube, water vapor is condensed which maintains the tube outer wall temperature of 99°C. Calculate the rate of condensation of water vapor (kg/second) 2 inch 2 inch 0,24 m/sec O
