Air flows through a constant area duct. the pressure and temperature of the air at the inlet to the duct are p1 = 100 kpa absolute, and t1 = 298 k, respectively. inlet mach number is m1 = 0.1. heat is transferred to the air as it flows through the duct and as a result the mach number at the exit increases. a)-find the pressure and temperature at the exit, while the exit mach number changes between m=0.2 to 0.99 with increments of m=0.01. b)-find the amount of heat that is transferred to the air per unit mass of air.
