A turbojet engine in a wind tunnel receives air at a velocity of U;= 100 m/s and a density of p.= 1 kg/m'. The velocity is uniform and the cross-sectional area of the approaching stream which enters the engine is A = 0.1 m². The velocity of the exhaust jet from the engine, however, is not uniform but has a velocity which varies over the cross-section according to: u. = 2U (I-YIR) where the constant U= 600 m/s and R...

Consider an air-breathing jet engine which is flying at a velocity of 180 meters per second. For every kilogram/second of air mass flow, a 0.04 kgm/sec mass flow of fuel is injected into the engine. The exhaust velocity is 500 m/sec; the entrance pressure equals the ambient pressure and the exhaust pressure is 0.9 times the ambient atmospheric pressure. The incoming air temperature is 300 K. The entrance area and exhaust areas are both one square meter. Determine (a) thrust...
