EXERCISES 1. Air at 25°C and 50% relative humidity flows over water surface measuring 12 m x 6 m at a velocity of 2 m/s. Determine the water loss per day considering flow direction is along the 12 m side. Diffusivity of water in air is 0.26 x 104 m²/s. Sc = 0.6 and Kinematic viscosity is 15.7 x 10 m/s. (Ans: 361.84 kg/day)
