Air with a stagnation temperature of 430o C and a stagnation pressure of 1.6 MPa enters a constant-area duct in which heat is transferred to the air. The Mach number at the inlet to the duct is 3 and the Mach number at the exit to the duct is 1. Determine the stagnation temperature and the stagnation pressure. Ignore the effects of friction.
