User Avatar

Asked by Wiki User

The fastest Boeing airplane is the Boeing 747-8. It has a top speed of approximately Mach 0.855, which translates to around 700 miles per hour.

What ground speed does a 747 need for liftoff?

User Avatar

Asked by Wiki User

A Boeing 747 typically requires a ground speed of around 180-200 knots (207-230 mph) for liftoff. This speed varies depending on factors such as aircraft weight, weather conditions, and runway length.

What is the rotate speed of an Boeing 787?

User Avatar

Asked by Wiki User

The rotation speed of a Boeing 787 during takeoff is typically around 150-180 knots (173-207 mph or 278-333 km/h), depending on the aircraft's weight and other factors. During rotation, the pilot gradually raises the nose of the aircraft to lift off the ground.

What is the zero lift drag coefficient of Boeing 747?

User Avatar

Asked by Wiki User

The zero lift drag coefficient of a Boeing 747 is approximately 0.022. This value represents the drag force experienced by the aircraft when it is not generating lift.

Why would ol higue be burning like cane fire?

User Avatar

Asked by Wiki User

In some Caribbean folklore, an "ol higue" is a type of vampire witch. If an ol higue is burning like cane fire, it could symbolize the destruction of evil or malevolent spirits. It may also represent the cleansing or purification of negative energies associated with the ol higue.

What is the stall speed of an airplane under a load factor of 4 if the unaccelerated stall speed is 70 knots?

User Avatar

Asked by Wiki User

The stall speed of an airplane is inversely proportional to the square root of the load factor. Therefore, with a load factor of 4, the stall speed would be 35 knots (70 knots / √4).

Why does jet fuel float on water?

User Avatar

Asked by Wiki User

Jet fuel is less dense than water, causing it to float on the surface. This is due to the fact that jet fuel consists of hydrocarbons that are lighter than water molecules. The difference in density between the two substances creates the floating effect.

What is the speed Boeing 747?

User Avatar

Asked by Wiki User

The cruising speed of a Boeing 747 is approximately 560 to 570 miles per hour (900 to 920 kilometers per hour).

What is the speed boing 747?

User Avatar

Asked by Wiki User

A Boeing 747 typically cruises at speeds around 560-570 miles per hour (900-920 kilometers per hour). The exact speed can vary depending on factors such as altitude, weather conditions, and weight of the aircraft.

How fast does a Boeing 747 take off speed?

User Avatar

Asked by Wiki User

A Boeing 747 typically takes off at a speed of around 180 to 200 knots (207 to 230 mph or 333 to 370 km/h) depending on its weight and other factors.

How does the 747 lift off the groung?

User Avatar

Asked by Wiki User

The 747 generates lift by increasing its speed and angle of attack. As the aircraft gains speed, the air flowing over the wings creates lift, allowing the plane to become airborne. The engines provide the necessary thrust to propel the aircraft forward for takeoff.

What is thrust by weight of Boeing 747?

User Avatar

Asked by Wiki User

The thrust generated by the engines of a Boeing 747 is typically around 56,000 to 63,000 pounds-force per engine. Each Boeing 747 aircraft is powered by four engines, so the total thrust produced by all engines combined is roughly 224,000 to 252,000 pounds-force.

How much does a Boeing 747 weigh in kilograms?

User Avatar

Asked by Wiki User

A Boeing 747 typically weighs around 393,000 kilograms when empty and can have a maximum takeoff weight of over 440,000 kilograms, depending on the model and configuration.

What is the surface tension of jet fuel?

User Avatar

Asked by Wiki User

The surface tension of jet fuel typically ranges from 20 to 30 mN/m (millinewtons per meter). This property is important for fuel atomization and combustion efficiency in jet engines.

How does the wing shape on an airplane affect its ability to hold weight?

User Avatar

Asked by Wiki User

The wing shape of an airplane, particularly its airfoil profile, affects its ability to generate lift. A curved or cambered wing shape helps generate more lift, allowing the airplane to carry more weight. Additionally, the wing design influences the distribution and efficiency of lift across the wingspan.

What is the lift off speed of a Boeing 747?

User Avatar

Asked by Wiki User

The lift off speed of a Boeing 747 can vary depending on factors such as weight, runway length, and weather conditions. On average, a Boeing 747 typically takes off at a speed between 160 to 180 knots (184 to 207 mph).

How does a Boeing 737 works?

User Avatar

Asked by Wiki User

A Boeing 737 works by utilizing jet engines to produce thrust, which propels the aircraft forward. The engines take in air, compress it, mix it with fuel, and ignite it to generate the power needed for flight. The wings generate lift as the aircraft moves forward, allowing it to take off, cruise, and land.

Sound made by things in words?

User Avatar

Asked by Wiki User

Onomatopoeia is the term used to describe words that mimic the sounds they represent, such as "buzz," "bang," or "meow." It adds a sensory element to writing, allowing readers to better visualize and experience the sounds being described.

What goes 700 MPH at ground level?

User Avatar

Asked by Wiki User

A commercial airliner, such as a Boeing 747, can reach speeds of around 700 MPH at cruising altitude.

How loud is a Boeing 747?

User Avatar

Asked by Wiki User

A Boeing 747 at 100 m distance can have a sound pressure level of L = 130 dBSPL.

Never forget to tell the distance of the measuring microphone from the sound source, because the closer you are the louder it is.

The sound pressure level decreases by 6 dB per doubling of distance from the source to 1/2 (50 %) of the sound pressure initial value.

The sound pressure decreases inversely as the distance increases with 1/r from the sound source.

What is the relation between net thrust and gross thrust in a ramjet engine?

User Avatar

Asked by Wiki User

Net thrust in a ramjet engine is the actual useful thrust generated for propulsion, while gross thrust is the total thrust including the contributions from ram pressure. The net thrust is the difference between the gross thrust and the drag of the engine itself. The net thrust determines the actual propulsion force available for moving the aircraft forward.

How is the speed of an aircraft measured?

User Avatar

Asked by Wiki User

The speed of an aircraft is measured using an airspeed indicator, which measures the speed at which the aircraft is moving through the air. Groundspeed, on the other hand, is the speed at which the aircraft is moving over the ground and is measured using GPS technology.
