Mechanical Engineering

Consider an airplane modeled after the twin-engine BeechcraftQueen Air executive transport. The airplane has the followingcharacteristics: weight is 38,220 N; wing area is 27.3 m2; aspectratio is 7.5; Oswald efficiency factor is 0.9; and zero-lift dragcoefficient CD,0 is 0.03.

1) Calculate the thrust required to fly at a velocity of 725km/h at standard sea level. Assume the value of ?? =1.225 kg/m3 at standard sea level. (Round the finalanswer to the nearest whole number.) The thrust required to fly ata velocity of 725 km/h at standard sea level is _______N.

2) Calculate the thrust required to fly with a velocity of 725km/h at an altitude of 4.5 km. Assume the value of ?? =0.777 kg/m3 at an altitude of 4.5 km. (Round the finalanswer to the nearest whole number.) The thrust required to flywith a velocity of 725 km/h at an altitude of 4.5 km is _______N.
