A room of dimensions 5m x 5m x 2.5 m contains an air-water vapor mixture at a total pressure of 95 kPa and a temperature of 15°C. The partial pressure of the water vapor is 1.4 kPa. Using the table properties of water, determine a) The humidity ratio of the air in the room b) The density of the dry air if Ra = 0.287 kJ/kgK c) The relative humidity of the air mixture d) The enthalpy of the air-water vapor mixture
