Pls. answer this ..Thank you! Two airstreams are mixed steadily and adiabatically. The first stream enters at 37 C and 32 percent relative humidity at a rate of 16 m3 /min, while the second stream enters at 13 C and 92 percent relative humidity at a rate of 25 m3 /min. Assuming that the mixing process occurs at a pressure of 1 atm, determine the specific humidity, the relative humidity, the dry-bulb temperature, and the volume flow rate of the mixture.
An air-conditioning system operates at a total pressure of one atmosphere and consists of a heating section and an evaporative cooler. Air enters the heating section at 10 °C and 70 percent relative humidity at a rate of 30 m3/min, and it leaves the evaporative cooler at 20 °C and 60 percent relative humidity. Use this information to answer the following question. Choose the nearest value given in (a) – (e).The rate of water added to air in the evaporative cooler (kg/min) is (a) 0.12 (b) 0.67 (c) 13 (d) 37 (e) 67

A cooling duct receives air at 1 atm, 32°C, and 70% relative humidity with a velocity of 120m/min. This air passes over cooling coils filled with flowing water. This steadily flowing water experiences a for temperature rise during its time in the cooling duct coils. Meanwhile, the airflow leaves the cooling section saturated at 20°C. Determine (a) the rate of heat transfer, (b) the mass flow rate of the cooling water, (c) the flow rate of any condensate formed, and (d) the exit velocity of the air stream. Assume the cooling water has constant specific heat. Feel free to use the psychrometric chart on the next page for the air properties.
