The amount of surface area required by a parachute depends on various factors such as the weight of the load it needs to support, the descent rate intended, and the design of the parachute. Generally, parachutes for humans typically range from 300 to 500 square feet in surface area.

How does air resistance work on parachutes?
Air resistance, also known as drag, acts in the opposite direction of an object's motion through the air. When a parachute is deployed, its large surface area creates a lot of drag, which helps slow down the descent of the jumper. The shape and design of the parachute also affect how much drag it generates.
Why the mass with no parachute fell fastest?
Mass is always drawn to other mass. This is what produces the effect of Gravity, which is responsible for pulling the mass downward. When falling, there is one major factor which controls how quickly it falls--friction. The greater the surface area of the object, the greater the friction of air passing it, and slowing it down. The parachute adds a great amount of surface area without much extra mass, so the air-resistance (friction of air against it) is much greater. This causes it's "terminal velocity" (the greatest speed at which it can fall) to decrease dramatically. The end result is that because of the "difficulty" the air has getting around and past the object as it falls, the object dropps much more slowly. Take away the parachute, and it will drop much more quickly.
How does the shape of a parachute affect how long it stays in the air?
Hey' I just did an experiment for grade 11 physics that i designed where i investigated the shape and size of the parachute. The shape of the parachute doesn't effect how long it stays in the air much. The main thing that the shape effects is the stability and the less stable the parachute the faster the person will fall. That is why parachutes are in that banana rectangle shape so that there is more stability to glide through the air, like a bird. As the shape changes how much drag there is. Circles are pure drag and take the longest to fall. McPhysics
What is called The total area of all surfaces or an object?
The total area of all surfaces of an object is called the surface area. It is a measure of how much exposed surface the object has.
What makes the parachute stay longer in the air?
The hemispherical shape of a typical parachute is associated with a very high drag coefficient, which means for any given wind speed and air density combination, the actual force of drag is very high. Also parachutes are typically large which makes the drag force proportionaly higher. What this all means is that the drag required for an unaccelerated decent (which is equal to the weight) can be acheived with a much slower speed through the air (a non life-threatening speed upon landing). An object moving slower takes more time to cover a constant distance, so the parachute carries its object in the air longer.
How much surface area required to generate one ton of steam?
It depends on how long you are prepared to wait!
Why would someone need to know the surface area of a box?
To know how much material is required to make the box.
Why parachute descends slowly whereas stone dropped from same height falls rapidly?
A parachute descends slowly due to its large surface area, which creates significant air resistance (drag) as it falls, allowing it to slow down and reach a stable descent speed. In contrast, a stone has a much smaller surface area relative to its weight, resulting in less air resistance. Therefore, the stone accelerates rapidly due to gravity until it reaches its terminal velocity, which is much higher than that of the parachute. This difference in drag effects explains the contrasting descent speeds.

How much surface area does the earth have?
the surface of the moon is 0.074 of earth's surface area
What is the measure of how much surface an object has?
Area is the measure of how much surface an object has.
Do cubes have the same volume and surface area?
Yes Volume: Is the amount it takes to build it. Surface Area: Is how much is on the surface.

What is the relationship between surface area and rate of evaporation?
Evaporation is a process that takes place at the surface of a liquid, therefore the rate of evaporation is directly related to the surface area. Twice as much surface area will give you twice as much evaporation.
