4. (a) If w is humidity ration, o is relative humidity, Pw is partial pressure of water vapor in the air, T is air temperature, and P is the total pressure of the air, derive that w = 0.62198Pw/(P - Pw). I (b) If P=101.3kPa, Q = 50%, w = 0.014 kg/kg dry air, find Pw. T, and Psal. (c) If P=101.3kPa, w = 0.008 kg/kg dry air, T= 25 °C, find 0. (d) In problem (c), if Tincreases from 25 to 35 °C, find o.
