Calculate the pressure at a height of 8000 m above sea-level if the atmospheric pressure is 101.3 kN/m² and temperature is 15°C at the sea-level assuming (i) air is incompressible, (ii) pressure variation follows adiabatic law, and (iii) pressure variation follows isothermal law. Take the density of air at the sea-level equal to 1.285 kg/m³. Neglect variation of gwith altitude. [Ans. (i) 607.5 N/m2, (ii) 31.5 kN/m?
