Two humid airstreams are adiabatically mixed at 1 atm pressure to form a third stream. The first stream has a temperature of 100°F, a relative humidity of 90 percent, and a volume flow rate of 3 ft³/s, while the second stream has a temperature of 50°F, a relative humidity of 30 percent, and a volume flow rate of 1 ft³/s. Calculate the third stream’s temperature and relative humidity. Use data from the psychrometric chart.

The third stream’s temperature is _________°F.

The relative humidity is___________ %.
