Unformatted text preview: the spanwise eciency factor is e ` = 0 . 98. For these conditions (a) What is the total lift generated by the wing (in pounds force)? (b) What is the parasite drag 1 (in pounds force) if the parasite drag coecient has the constant value (independent of angle of attack) of C D p = 0 . 0190? (c) What is the value of the induced drag coecient? (d) What is the total drag force (in pounds)? (e) What is the ratio of lift to (total) drag? 3. Problem 5.34 in Anderson. 1 The total drag often is represented as the sum of the parasite drag D p and the induced drag D i , having corresponding drag coecients C D p and C D i such that D = D p + D i = 1 2 V 2 S ( C D p + C D i ) ....
