The total wing area of a Boeing B-29 is 1736 ft. The fully loaded take-off mass of a B-29 is 6.25 x 104 kg. The cruising speed of the B-29 is 275 mi/h. At cruising altitude, the air temperature is 251 K and the air pressure is 6.16 x 10Pa. a. Use the density form of the ideal gas law (assuming the average molar mass of the air is 0.0288 kg moll) to compute the air density at cruising altitude...

Approximately what size wings would an aircraft need on Mars if its engine generates the same differences in speed as in the "Practice It" ( wing area: 3.50 m2, air flows over the top of the wing at 246 m/s, air flows underneath the wing at 223 m/s) and the total mass of the craft is 300 kg? The density of air on the surface of Mars is approximately one percent Earth's density at sea level, and the acceleration of...

PRACTICE IT
Use the worked example above to help you solve this problem. An
airplane has wings, each with area 4.05 m2, designed so
that air flows over the top of the wing at 249 m/s and underneath
the wing at 226 m/s. Find the mass of the airplane such that the
lift on the plane will support its weight, assuming the force from
the pressure difference across the wings is directed straight
upwards.
Your response differs from the correct...
