Problem 14.7: An air-conditioning system operates at a total pressure of 95kPa and consists of a heating section and a humidifier that supplies wet steam (saturated water vapor) at 100°C. Air enters the heating section at 10°C and 70 percent relative humidity at a rate of 35 m'/min, and it leaves the humidifying section at 20°C and 60 percent relative humidity. Determine (a) the temperature and relative humidity of air when it leaves the heating section, (b) the rate of...
Problem 4- A HVAC system is operating in heating mode with a steam humidification system, as shown below. Air enters the system at 10°C and 70% relative humidity at a rate of 35m3/min. After heating and subsequent humidification by saturated water vapor at 100°C, the air leaves the system at 20°C and 60% relative humidity. Find (1) the temperature and relative humidity of the air when it leaves the heating section, (2) the heat transferred to the air in the...
Air enters a heating and humidification system at 5◦C, 50% relative humidity. The air first passes over a heater, and is then humidified with steam. The steam is supplied at 200 kPa pressure and 300◦C. The air leaves the system at 30◦C, 60% relative humidity. (a) Determine the heat transfer to the air, per unit mass dry air. (b) Determine the temperature and relative humidity of the air leaving the heating section (i.e., prior to the humidification section). (c) Determine...
An air-water vapor mixture enters a heater-humidifier unit at 5°C, 100 kPa, 50% rh. The flow rate of dry air is 0.1 kg/s. Liquid water at 10°C is sprayed into the mixture al the rate of 0.0022 kg/s. The mixture leaves the unit at 30°C, 100 kPa. Calculate (a) the relative humidity at the outlet (b) the rate of heat transfer to the unit
please solve it quickly ignore p=75 Problem 3 Part a P=57 Moist air enters the cooler of an air conditioning unit at 25 °C and a relative humidity of 70%. The cooled and dehumidified air leaves the cooler saturated at 18 °C. The temperature of condensed water is 18 °C. The pressure is constant at 101.325 kPa. The mass flow rate of the dry air is mda=67 kg/s. Use the psychometric chart to determine a) The humidity ratio at the...
3. (45) Operating data for an air-conditioning process is shown below. Air flows through a soaked pad and then a heating section. The device is well-insulated and the volume flow rate of the incoming moist air is 150 m3/min. Please determine (a) (6) The humidity ratio of the incoming and exiting air.

3. The outdoor air enters an AC system at 10°C and 75% relative humidity at a steady rate of 26 m3/ min, and it leaves at 25°C and 45% relative humidity. The outdoor air is first heated to 21°C in the heating section and then humidified by injection of hot steam in the humidifying section. Assuming the entire process takes place at 1 atm, determine (a) the rate of heat supply in the heating section, and (b) the mass flow...
