Anorthrup f-5 fighter aircraft has an approximate wing area of 225 ft^2. if the airplane weighs 15,000 lb and is flying in level flight at mach 2.2 at a standard altitude of 33,000 ft., estimate the wave drag on the wings assuming they behave as a flat plate.

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

Fluids at rest possess no flow energy. a)- true b)- false

Ahot wire operates at a temperature of 200°c while the air temperature is 20°c. the hot wire element is a tungsten wire of 5 um diameter and 2 mm in length. plot using excel current, heat transfer and heat generated by the wire for air velocity varying from 1-10 m/s in steps of lm/s? matlab the sensor voltage output, resistance, or assume nu 0.989 re033pr13 take air properties at tr (200°c20°c)/2 = 110°c properties of tungsten: c 0.13 kj/kg.k 3 p 19250 kg/m k (thermal conductivity) = 174 w/m.k
