The latest weather report states that the temperature is 24°C and the relative humidity is 50%.

(a) Use the psychometric chart to estimate the absolute humidity, humid volume, specific enthalpy, wet-bulb temperature, and dew-point temperature of the air.

(b) A thermometer is mounted on the back porch of your house. What temperature would it read?

(c) A sample of outside air is cooled at constant pressure. At what temperature would condensation begin?

(d) You step out of your neighborhood pool and feel quite cold until you dry off. Explain why. Estimate your skin temperature while you were still wet. Explain your answer. What would be different if the relative humidity were 98%?
