At cruise conditions, air flows into a jet engine at a steady rate of 60 lbm/s. fuel enters the engine at a steady rate of 0.58 lbm/s. the average velocity of the exhaust gases is 1535 ft/s relative to the engine. if the engine exhaust effective cross-sectional area is 3.3 ft2, estimate the density of the exhaust gases in lbm/ft3.
