What is the name for the surface area of a dimpled surface?
The surface area of a dimpled surface is often referred to as the "effective surface area." This term accounts for the increased area created by the dimples compared to a smooth surface of the same overall dimensions. In contexts like aerodynamics or fluid dynamics, this effective surface area can influence factors such as drag and lift.
How does surface area affect lift and drag?
Surface area significantly influences both lift and drag in aerodynamics. A larger surface area can increase lift by providing more space for air to flow over and generate upward force, which is crucial for aircraft performance. However, increased surface area also leads to higher drag, as there is more resistance against the air, particularly at higher speeds. Balancing these effects is essential for optimizing the design of wings and other aerodynamic surfaces.
How much pressure is required to lift one ton?
Assuming you need a metric ton, that's 1000 kilograms. To lift that, you need a FORCE of 9800 newtons. Force is related to pressure by: pressure = force / area, so the answer to the original question would depend, over what area the force is applied.
What is a sloping surface used to move heavy loads up or down?
A sloped surface is used to help lift a load up.
At what height above the surface of the earth does the balloon have a speed of 9.00 meters per second?
If you mean vertical speed, you would need to know the amount of lift it's generating, its cross-sectional area and its drag factor (at least!). More info needed.
How many balloons would it take to lift up the average house?
It would take thousands of balloons to lift up the average house, as houses are heavy and balloons can only lift a small amount of weight. The exact number of balloons required would depend on the size and weight of the house, but it would be an impractical and unsafe way to try to lift a house.
How many balloons can lift a child?
The number of balloons needed to lift a child would depend on the weight of the child and the size of the balloons. On average, it may take around 80-100 helium-filled balloons to lift a small child off the ground. It's important to consider safety measures and proper balloon handling if attempting such a stunt.
How many helium balloons would you need to fly in the house?
The number of helium balloons needed to lift a person will depend on the person's weight. On average, it takes about 3-5 large helium balloons to lift 1 pound. For example, to lift a 150-pound person, you would need roughly 450-750 balloons. It is important to consider factors like air currents and ceiling height when attempting to lift objects with helium balloons indoors.
How many balloons does it takes to lift 1 pound?
it took 53 12" helium balloons to lift a pound, you have to add the weight of the string and balloons
How many helium balloons does it take to lift the Titanic?
10000000 helium balloons
Can Balloons Really Lift A Person Off The Ground?
No, balloons cannot lift a person off the ground. The amount of lift produced by balloons is not enough to support the weight of a person. Additionally, the laws of physics would make it impractical for balloons to overcome the force of gravity acting on a person.
Why do bigger balloons take longer to fall?
Bigger balloons displace more air, creating more resistance against gravity, which slows down their descent. This increased surface area-to-weight ratio also helps them generate more lift, further reducing their fall speed.
How lift produced in aircraft?
lift = 1/2 air density x velocity squared x surface area
