Question

Figure shows data for a portion of the ducting in ventilation system operating at steady state. The ducts are well insulated and the pressure is very nearly 1 bar throughout. Assuming the ideal gas model for air with Cp = 1 kJ/kg · K. and ignoring kinetic and potential energy effects, determine:

(a) the temperature of the air at the exit, in °C.

(b) the exit diameter, in m.
