Structural Mechanics

An aircraft is flying at an altitude of 4500 m above sea level, where the ambient pressure, temperature and density are 57 kPa, 259 K and 0.777 kg/m3, respectively. The speed of the aircraft (V) is 230 m/s. Gas constant R= 287 J/kg/K, and specific heat ratio 𝛾 = 1.4. If the stagnation pressure is po, and static pressure is p, the value of [ po-p 1 2𝜌V2 ] is ________ (rounded off to two decimal places).
