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...

2. An aircraft with a single turbojet engine (with an inlet area of 1 m2) is flying at cruising condition with a flight Mach number of 0.7. The ambient temperature and pressure are 250 K and 100 kPa, respectively. The engine compressor pressure ratio is 12, and the turbine inlet temperature is 1200 K. Assume all mechanical components are operating at isentropic condition and the specific heat can be considered a constant (throughout the entire engine) of 1 kJ/(kg K)....

1. Consider a design of a low-speed open-circuit subsonic wind tunnel. The goal is to achieve a free stream velocity of 150 m/s at the test section of this tunnel. This wind tunnel is equipped with a U-tube mercury manometer that measures the pressure difference between the inlet (the settling chamber) and the test section. If the fan of the wind tunnel is able to generate the maximum pressure difference corresponding to a height difference of 10 cm on the...
