The temperature of air in a room is 55°C and the total pressure is 1.013 x 105 N/m ² abs. The air contains water vapor with a partial pressure = 4660 N/m². Calculate (i) the humidity in mass and molar terms (ii) the saturation humidity and dew point (iii) percentage humidity and the percentage relative humidity (vapor pressure of water at 55° C is 118 mm Hg). (4+2 +2=8) Also find out from psychrometric chart: (iv) humid volume and (v) enthalpy. State the equations to obtain them mathematically.
