12.81 At steady state, a moist air stream (stream 1) is mixed
adiabatically with another stream (stream 2). Stream 1
is at 13°C, 1 bar, and 20% relative humidity, with a
volumetric flow rate of 0.3 m²/s. A single stream exits the
mixing chamber at 19°C, 1 bar, and 60% relative humidity,
with a volumetric flow rate of 0.7 m'/s. Determine for
1o stream 2
(a) the relative humidity.
(b) the temperature, in °C.
bi (c) the mass flow rate, in kg/s.
