Air, at $450 \mathrm{~K}$ stagnation temperature and at a rate of $50 \mathrm{~kg} / \mathrm{s}$, enters the combustor of a turbofan engine and is burned with $1 \mathrm{~kg} / \mathrm{s}$ of Aviation Kerosene (Heating value $44 \mathrm{MJ} / \mathrm{kg}$ ). The specific heat at constant pressure for the incoming air and the burned products are $1.005 \mathrm{~kJ} / \mathrm{kgK}$ and 1.147 $\mathrm{kJ} / \mathrm{kgK}$ respectively. Considering $100 \%$ burner efficiency, the stagnation temperature at the exit of the combustor is equal to ____________________$\quad \mathrm{K}$. (in one decimal place).
