At an elevation of 5 ,000 m, a ir and fuel flow into a jet engine on a plane and leave as hot exhaust . t he plane ’ s speed is 8 00 km/hr , relative to the ground . at the engine a ir intake, a = 2 .00 m 2 . the fuel use i s 9,500 kg/hr. at the exhaust, a = 0.8 m 2 and v = 1,100 km/hr relative to the ground . what is the density of the exhaust? assume the intake and exhaust pressures are at the u. s. standard atmosphere conditions (table c.2) . (note the exhaust is a mixture of air, co2 and water vapor.)
