Temperature (K) For this problem, you may neglect any heat transfer, as well as neglect kinetic energy except at the outlet (state 5). Use the tables for obtaining properties (do not assume constant specific heat). Assume air is an ideal gas with ideal gas constant of R = 0.287 kJ/kg-K. Use the appropriate conservation equations and make approximations (and In a similar manner, find the turbine specific work. And finally, using similar arguments, find the nozzle exit velocity.
