Atmospheric air at 30°C and with a density of 1.12 kg/m³ enters an air-conditioning unit through a cross- sectional area of 0.06 m- at a velocity of 10 m/s. Water is removed from the air and leaves the air- conditioning system as a liquid at a rate of 45.5 kg/h. The air that leaves the unit is at 15°C and has a densitzof L21 kg/m² The discharge cross-sectional area is 0 075 m² Determine the velocity of the air leaving. Air Air Water
