Problem 6. Air at standard temperature and pressure is drawn steadily from a large room through an isentropic-converging nozzle into a frictionless, constant area duct with an inlet at Section (1) and an outlet at Section (2)The flow in the duct is diabatic (912 = 500 kJ/kg). For maximum flowrate, calculate at Section (1) andSection (2) (a) stagnation temperature and stagnation pressure, (b) static temperature and static pressure, and(c) flow speed. (d) Sketch the T-s diagram from the large room to Section (2). (e) Briefly discuss what will happen ifyou try to add more thermal energy to the flow with fixed room conditions for the case where the mass flowrateis also fixed and for the case where mass flowrate can change.
