St. Gotthard Between 30,000 and 40,000 feet (9,000 and 12,000 m), the cruising altitude of most jet aircraft, air temperature ranges from -40 F to -70 F (-40 C to -57 C). 7 Our calculations also indicate that variations in the activity of a volcano must be reflected in the temperature gradient of the vicinity, and that three observations of the temperatures at' depths of 16 feet and 50 feet should suffice to determine to a fair degree of accuracy the location ar:d form of the subterranean mass of liquid lava. From the foregoing considerations it is evident that the abnormal temperature gradients can be explained very simply and without the introduction of new hypotheses, by the varying production of heat in coal seams, the proximity of volcanic masses, and the cooling effect of large bodies of water. Simplon 50.0 What Are The Largest Sources Of Error In This Experiment. 20000 ft = 6096 meters. The International Union of Pure and Applied Chemistry (IUPAC) defines the air density differently. who had obtained his data from Hungarian mining engineers. One blank to convert to the human eye c ) relatively small changes in temperature from to! On a standard day, the temperature at 40,000 feet is approximately -69.7F. What do you mean by humidity? for such causes of error as the heat produced by the drill, or currents of air and water in the borings could scarcely change the temperature by more than 3 or 4 deg. Finishing and Plating Volume = 1 1000 = 1000mL. K is the specific gas constant. This difference is insignificant enough that we can usually ignore it and use the standard atmospheric model as is. 33.4 The rear gunners of Lancaster bombers were often exposed to temperatures of minus 86F to minus 104F . Assuming the air temperature of 20 C, the speed of sound is: You can derive these results by applying the formula c_air = 331.3 (1 + T/273.15), where T = 20C. 0.021 to 0.0316 I- In coal and oil fields. That point is around 28,000 to 30,000 feet. The outside temperature during this time is an average minus 44.6C, which is why the cargo hold is pressurized as well. To convert temperatures in degrees Fahrenheit to Celsius, subtract 32 and multiply by .5556 (or 5/9).
