Unformatted text preview: b) Find the density altitude, the altitude in the standard atmosphere at which the density would be the same as it on the “nonstandard” day in Boston. (Use SI units). Departing Boston on a hot summer day is equivalent to departing an airport (at the density altitude you will find) on a standard (15°C) day. 4. Anderson problem 5.3. Find lift and drag (in N). Ignore the part about finding the moment. Also find L/D. Note that Example 5.1 is very similar to this problem. However, the example assumes “standard sea-level conditions” which do not pertain for this problem because the temperature is non-standard (for sea-level) 303 K . So you must first determine the corrected value of free stream density ± ² . 5. Anderson problem 5.4...
