Air at temperature 300 K is compressed isentropically from a pressure of 1 bar to
10 bar in a compressor. Eighty percent of the compressed air is supplied to a
combustor. In the combustor, 0.88 MJ of heat is added per kg of air. The specific
heat at constant pressure is Cp = 1005 J/kg/K and the specific heat ratio is γ = 1.4.
The temperature of the air leaving the combustor is ___ K (rounded off to one
decimal place).
