A medium-sized jet has a 3.8-m
m-diameter fuselage and a loaded mass of85,000kg
kg.The drag on an airplane is primarily due to the cylindrical fuselage, and aerodynamic shaping gives it a drag coefficient of 0.37.
How much thrust must the jets engines provide to cruise at230m/s
m/sat an altitude where the air density is1.4kg/m
3
kg/m3?
