Air at 90°F (27°C) and 14.7 psia (101.3 kPa) is heated by passing over a steam coil. If steam enters the coil at 30 psia (210 kPa), 400°F (205°C), and 30 lb/min (0.23 kg/s) and leaves at 25 psia (175 kPa) and 200°F (94°C), what is the air mass flow rate that produces a leaving air temperature of 140°F (60°C)?
