Question
The figure shows data for a portion of the ducting in a ventilation system operating at steady state. The ducts are well insulated and
the pressure is very nearly 1 atm throughout. The volumetric flow rate entering at state 2 is AV₂ = 3600 ft3/min. Assume the ideal gas
model for air with cp = 0.24 Btu/lb-ºR and ignore kinetic and potential energy effects.
1
(AV)₁ = 5000 ft³/min
T₁ = 80°F
2
(AV) ₂
T₂ = 40°F
ft³/min
Air, Cp=0.24 Btu/lbºR
p=1 atm
Insulation
3 V3400 ft/min
T3 = ?
Determine the temperature of the air at the exit, in °F, and the rate of entropy production within the ducts, in Btu/min.°R.
