Question

Aeronautical Engineering (MECH ENG 3100 & 7066) Assignment 2 Due: 3 May 2019 @ 5pm (Electronic submission via Canvas) 1. A Boeing 777 has a wing planform area of 4000f1? and a takeoff weight of 550,000lb. a. Assuming a velocity of 260km/h and L = W at takeoff, calculate the lift coefficient at takeoff for a hot & high condition of h Compare the above result with the lift coefficient for cruise at Mach number of 0.70, altitude of 30,000ft and OAT of-45°C, assuming 95% of the takeoff weight. 1000m and t 35°C b.

can the density calculation be clearly expressed please.
