Question 3 CO2 enters a constant area duct at the temperature of 172C, pressure of 690 kPa, and the flowrate of 548.64 km/hr. Further downstream the properties change to 304.8 m/s and 505C. calculate: 3.1. 3.2. Pressure (P2) at section 2 The change in enthalpy between sections Entropy changes between the sections The mass flow per unit area. (3) (3) (3) (3) 3.3. 3.4. = Use R = 0.1889 kJ/kg-K and k = 1.3 for carbon dioxide. [12]
