a Air at stagnation temperature 323 K and stagnation pressure 600 kPa flows isentropically through a converging nozzle, as shown in the figure. The nozzle feeds a frictionless, constant- area circular duct having diameter D= 0.02 meters. Heat transfer to the duct occurs at a rate 192 = + 200 kJ /kg Determine the maximum mass-flow-rate through the system, and the range of back-pressures which will allow this maximum mass-flow-rate. Determine the stagnation temperature and stagnation pressure at the exit of the duct (for maximum mass-flow-rate).
