An airplane is consuming fuel at a rate of 8 gal/min when cruising at a constant altitude of 10,000 ft at constant speed. assuming the drag coefficient and the engine efficiency to remain the same, determine the rate of fuel consumption at an altitude of 30,000 ft at the same speed. take the density of standard air as rho1 = 0.05648 lbm/ft3 at 10,000 ft and rho2 = 0.02866 lbm/ft3 at 30,000 ft.
