| | Problem C: (Estimated time of completion 3 seconds*) | | | | At what Geometric Altitude will the density of the air be half of what it is at sea level? | | | | | 1. Place cursor in front of the number in the row for Density Ratio. Highlight the number in that box. | | | | | | 2. Type in the desired value (in this case 0.5 since the density will be half as the reference density at sea level). | | | | | | 3. You are done! Just read the desired results from the corresponding rows. In this case we wanted Geometric Altitude. The Geometric Altitude is 6,669.8 m, 21,882.5 ft, or 4.1444 sm. | | | | Important: There are times when a problem may have multiple solutions. For example there are two altitudes in which the temperature is -2.5 oC. At 8,836.7 ft and 168,676.1 ft, yet if you input - 2.5 oC on the Temperature row you will always get the solution that lies at the lowest altitude, that is, 8,836.7 ft. This is always true for all other properties that have multiple solutions. | previous | | 1 2 3 4 5 | | next | 3/5 Note that it does not matter the order that you enter the rows. The remaining row (field) will be calculated based on the values of the other two rows when the Eval button of that row is pressed. * Time estimates are based on a person that already knows how to use the web site. |
