The barometer of an aeroplane on the apron of an airport 1 000 m above sea level shows 89.9 kpa. the outside temperature is 9°c. assuming the temperature lapse rate to be 0.0065k/m, calculate: a) the height of the aeroplane above a mountain peak that is 2 500 m above mean sea level, as it passes over it, if the barometer then indicates a pressure of 65,5 kpa. take the gas constant [947.7m] for air to be 287 j/kg, k b) the air temperature at flight altitude in °c.
