An airplane has an effective wing surface area of 21.9 m2 that is generating the lift force. In level flight the air speed over the top of the wings is 70.0 m/s, while the air speed beneath the wings is 47.0 m/s. What is the weight of the plane?
For an airplane in flight, the average speed of the air relative to the plane is 317 m/s below the wings and 348 m/s above the wings. The bottom of each wing has a surface area of 29.9 m2. Calculate the lift, which is the net upward force of air on the plane.
An airplane wing generates lift due to a difference in air speed above and below the wing. If the wings are both at the same height, what term is the same on both sides of the Bernoulli equation? Calculate the change in pressure (P-bottom - P_top) a wing experiences if the air moves at 245 m/s above the wing and 222m/s below the wing. The density of air is 1.29kg/m^3. Calculate the lift force the plane experiences if it has...
For an airplane in flight, the average speed of the air relative to the plane is 306 m/s below the wings and 336 m/s above the wings (see the figure below). The bottom of each wing has a surface area of 29.7 m2. Calculate the lift, which is the net upward force of air on the plane.
For an airplane in flight, the average speed of the air relative to the plane is 320 m/s below the wings and 352 m/s above the wings (see the figure below). The bottom of each wing has a surface area of 30.9 m2. Calculate the lift, which is the net upward force of air on the plane.
A U-tube contains liquid of unknown density. An oil of density 770 kg/m³ is poured into one arm of the tube until the oil column is 13.5 cm high. The oil-air interface is then 4.5 cm above the liquid level in the other arm of the U-tube. Find the density of the liquid. A raft is made of 11 logs lashed together. Each is 38.0 cm in diameter and has a length of 7.00 m. How many people (whole number)...
If air flows under the wing of.an 80,000 kg plane with a speed of 280 m/s how fast does it need to flow over the top of the wing in order to keep the plane in the air if the wings have a surface area of 60 m2?
A small jet airplane has a total wing area of 62.5 m2 and a mass of 7.03 104 kg. (a) If this jet is in horizontal flight, determine the pressure difference between the lower and upper surfaces of the wings. (b) When the speed of air traveling over the wing is 237 m/s, determine the speed of air under the wing. Use 1.29 kg/m3 as the density of air.
An airplane wing is designed so that the speed of the air across the top of the wing is 283 m/s when the speed of the air below the wing is 223 m/s. The density of the air is 1.29 kg/m3. What is the lifting force on a wing of area 22.0 m2?
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...
