The atmospheric pressure at the sea-level is 101.3 kN/m² and the temperature is 15°C. Calculate the pressure 8000 m above sea- level, assuming (i) air is in compressible, (ii) isothermal variation of pressure and density, and (iii) adiabatic variation of pressure and density. Assume density of air at sea-level as 1.285 kg/m³. Neglect variation of 'g' with altitude. [Ans. (i) 501.3 N/m², (ii) 37.45 kN/m² (iii) 31.5 kN/m²]
