PH) 3) Air at a temperature of 60 F and a relative humidity of 60% with a flow rate of 1000 # 3/min enters a warm-air furnace and humidifier unit. The air leaves the unit at a temperature of 120 F and a relative humidity of 12%. If the air flows through the unit at a pressure of 14.5 psia and if the water is supplied to the humidifier at 65 F, using the appropriate equations, determine: a) the mass...

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...

Please answer the relative humidity
A humidifier takes in moist air at 29 °C, 1 bar, and 50% relative humidity with a volumetric flow rate of 13 m3/s. To increase the moisture of the air, liquid water at 40 °C is sprayed into the moist air witha flow rate of 22 kg/s. Some of the liquid water evaporates into the moist air stream and the rest drain:s out of the humidifier with a temperature of 26 °C and a mass...

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...

Anair-conditioning system operates at a total pressure of 1 atm 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 mP/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 heat...

2. An air conditioning system is to take in air at latm 33C, 70% relative humidity and flow rate of 50m3/min and deliver it 23C and 60% relative humidity. The air first flows over the cooling coils, where it is cooled and dehumidified, and then over the resistance heating wires, where it is heated to the desired temperature. Assuming that the condensate is removed from the cooling section at 10C, determine: a) The temperature of the air before it enters...

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...

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...
