Problem 2An airplane has a mass of 1.2 million grams and is cruisinghorizontally at an altitude of 23000feet at a speed of 205 miles per hour. Each wing has a width of 6ft and extends 18 ft from thefuselage on each side. What is the drag force on the plane due tothe wings and what is thehorsepower needed to overcome this force?For this problem, the air density is 0.0657 lbm/ft3 and theviscosity is 0.000000364 lbf s/ft2.Also calculate the lift coefficient (CL) for this aircraft. Notethat the lift force (FL) for an airplaneis given by the following equation: ๐น๐ฟ = ๐ถ๐ฟ ๐ด๐๐ (๐๐22 ) where Apl is the planform area which is 108ft2 for this application and rho is the air density.
