SUMMARY
This discussion focuses on calculating the inlet and outlet gas relative humidities when air is compressed to 10 atmospheres and cooled to 25 degrees Celsius. The initial moisture content of the molecular sieve is specified as 8 lb water per 100 lb sieve, with a saturation vapor pressure of water at 25°C being 24 mmHg. The application of Fick's first law and mass balance principles is essential for determining the relative humidities in this scenario. The height of the transfer unit is noted as 3 inches, which is critical for the calculations.
