2.14 From observation it is found that at a certain altitude in the atmosphere the temperature is 25C and the pressure is 45.5kNm2, while at sea level the corresponding values are 15C and 101.5kNm. Assuming that the temperature decreases uniformly with increasing altitude, estimate the temperature lapse rate and the pressure and density of the air at an altitude of 3000m. [6.37C per 1000m,70.22kNm2,0.91kgm3]
