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 = 4400 ft3/min.  Assume the ideal gas model for air with cp = 0.24 Btu/lb·oR and ignore kinetic and potential energy effects.  Determine the temperature of the air at the exit, in oF, and the rate of entropy production within the ducts, in Btu/min·oR

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 = 4400 ft3/min.  Assume the ideal gas model for air with cp = 0.24 Btu/lb·oR and ignore kinetic and potential energy effects. 



Determine the temperature of the air at the exit, in oF, and the rate of entropy production within the ducts, in Btu/min·oR.
(AV)1 = 5000 ft³/min Air, Cp = 0.24 Btu/Ib°R p=1 atm 1 T, = 80°F 3 V3 = 400 f/min T3 = ? 2 (AV)2 T2 = 40°F -Insulation ft/min
Transcribed Image Text:(AV)1 = 5000 ft³/min Air, Cp = 0.24 Btu/Ib°R p=1 atm 1 T, = 80°F 3 V3 = 400 f/min T3 = ? 2 (AV)2 T2 = 40°F -Insulation ft/min
