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...

Be sure to answer all parts. On a humid day in New Orleans, the temperature is 23.0°C, and the partial pressure of water vapor in the air is 39.0 torr. The 9,000-ton air-conditioning system in the Louisiana Superdome maintains the inside air temperature at the same 23.0°C, but produces a partial pressure of water vapor of 10.0 torr. The volume of air in the dome is 2.4 x 106 m, and the total pressure inside and outside the dome are...

Question 4 a. A vessel contains a gaseous mixture of composition by volume 80% H2, and 20% CO. It is desired that the mixture should be made in the proportion 50% H2 and 50% CO by removing some of the mixture and adding some Co. Calculate, per kilomole of mixture, the mass of mixture to be removed and the mass of CO to be added. The pressure and temperature in the vessel remain constant during the process. Take the molar...
