Consider the steady-state flow in a combustion chamber where heat is added by burning fuel. neglect friction and consider that the thermodynamic properties of the combustion gases are the same as those of air. data: m1 = 0,4; p1 = 557kpa; t1 = 604k; t2 = 900k; a = 0,0185m²; find: a) mass flow rate; b) m2; c) the addition of heat per unit mass and the rate of heat exchange; d) express the rate of heat addition as a fraction of the maximum rate of heat addition
