• Soru : Standart atmosfer şartlarında deniz seviyesine göre 15.000 metre yükseklikteki

Question: At an altitude of 15,000 meters above sea level in standard atmospheric conditions; a) What is the temperature value? (Temperature will be calculated in ℃.) B) What is the pressure value? c) What is the density value?

STP is sea level    T = 0^o C       or  273.15 K

standard lapse rate for temperature is approx  9.8 degree C per 1000 m

0 - 9.8(15) =  - 147^o C

   if you are using 15^o C for standard temp at sea level     the answer would be   -132 degrees C
