Free surface effect affects the stability of a system due to change in centre of gravity of the system. it is generally used in respect of ships and crafts. The change in centre of gravity occur due to change in distribution of mass when a ship make movement. This movement may be due to sharp turns (operational) or due to the natural reasons such as wind or wave forces acting on the ship. The mass distribution in a ship changes due to the liquid heads available in the ship makes the movement. Since, the liquid head keeps it level in line with waterline thus centre of gravity of liquid mass moves with the movement of liquid head in the ship. This typically happens in the cases when ship is holding partially filled fuel tanks and water tanks. This causes instability and may leads to overturning of ship. To prevent the same, smaller capacity tanks are being used distributed properly arround the centreline. The hull should also be kept watertight under bad weather conditions

Do gases have free surface?
Gases cannot form a free surface on their own. However, gases do have a free surface at the boundary between gas and liquid, such as the free surface of the sea, or the boundary between the liquid of a soft drink and each carbon dioxide bubble rising in it.
How do particles move in a surface wave?
Surface Waves can propagate only along the boundary of solid.Two types are:Rayliegh Waves propagate along boundary between two dissimilar solid media, in a plane perpendicular to the surface and containing the direction of propagation.Love Waves are polarized shear wave with an associated oscillatory particle motion parallel to the free space and perpendicular to the direction wave motion.
What are the differences between free settling and hindered settling?
when the particle do not collide with the wall of the container or with the other particles is called free settling the suspended particles in the medium do nor effect it and when the particle collide with the other particles and with the wall of the container an d collides with the suspended particles is called hindered settling
Liquids form spherical drops because of what property?
Liquids tend to form spherical droplets because of surface tension. There is energy associated with the surface tension, and since a sphere has the minimum surface to volume ratio, it has the minimum surface tension related energy for a given amount of liquid. (It is a general principle in physics that things tend toward a minimum energy state.)
If a small diameter open glass tube is partially immersed in a vessel containing mercury the surface of the mercury inside the tube will be?
Lower at the inside (convex) than the 'free' mercury at the outside (concave) , because of interaction forces with glass (side) and air (on top), surface tension of mercury and the high density.

Why free surface effect is detrimental in ro-ro ferries?
RO-RO ferries have large open decks (car decks) without any sub division or bulkheads. Hence a small amount of water would be able to impart a significant free surface effect.
What is free surface in stability?
Free surface in stability refers to the unconfined surface of a liquid on board a vessel that can cause instability. When a vessel rolls or pitches, the liquid's inertia can lead to shifting, creating a destabilizing effect. To prevent this, it is important to minimize free surface by properly securing liquid cargoes and maintaining proper vessel stability.
What is the effect of slack tank?
As the vessel rolls the fluid in any slack tanks can shift to the low side moving the center of gravity towards that side. This is called the free surface effect. When the CG shifts it reduces the righting moment making the vessel more unstable.
What is free surface?
An epithelium always has on surface where the cells are exposed either to the external environment or to an internal passageway or cavity; this surface is called the free surface of the epithelium.
Do gases have free surface?

Are you in free fall if you use a parachute?
interesting: in effect you are, because you have reached the terminal velocity for your surface area, which happens to be very large! if wrong, someone please correct me.

What is the free surface of liquids?
The free surface of a liquid is the upper boundary of the liquid where it meets the air or another medium. It is the surface that is not confined by a container and is therefore free to move and change shape in response to external forces, such as gravity.
What are three reasons why you have tides?
# Free surface water # Masses in separate locations # The body with free surface water is rotating.
What is a water break free surface?
has to do with alkaline dip tanks.. Water break free surface is a 10 second retention of water on a surface that has been cleaned and rinsed of its alkaline.
What is the difference of the earth and the sun's surface?
You can still get free parking on the suns surface.
