Moist air is at 80F (26.67C) dry-bulb, 0.0150 lb-w/lb-da (0.0150 kg-w/kg-da) humidity ratio, pressure of 14.696 psia (101.35 kPa). Determine the dew-point temperature, relative humidity, volume in cu ft/lb-da (cu meters/kg-da), and enthalpy in Btu/lb-da (kJ/kg-da) using the moist air property tables and the ideal gas equations. What error is incurred using the ideal gas approach? Compare these results with the psychrometric charts (available in ASHRAE Fundamentals)
