Question

Transcribed Image Text:68 m3/s of air enters a combustion chamber of a jet
engine at a velocity of 418 m/s at -59 °C and 31 kPa.
The air leaves the chamber at 944 m/s at 187 °C.
Determine the fuel (in kg) consumed during a 30
minute flight. Assume that changes in air mass flow
rate through the chamber are not significant and
Ah = CPAT. Take the air gas constant to be 0.287
kPa.m3/kg.K, the specific heat of air to be 1 kJ/(kgK)
and the heating value of the fuel to be 42,024 kJ/kg.
Give your answer to the nearest kg.
