Supply air at 18°C dry-bulb and RH of 80% flows through a duct whose inside wall temperature is about 11°C. Will water droplets form inside the duct? Return air at 25°C and fresh outdoor air at 35°C is mixed in an adiabatic mixing chamber. If 22% of the mixed air is from outdoor air, what is the temperature of the mixed air in °C?

Supply air at 18°C dry-bulb and
RH of 80% flows through a duct
whose inside wall temperature is
about 11°C. Will water droplets
form inside the duct?
Return air at 25°C and fresh
outdoor air at 35°C is mixed in an
adiabatic mixing chamber. If 22%
of the mixed air is from outdoor
air, what is the temperature of
the mixed air in °C?
