I dont mean to be offtopic but does someone know of a method to get back into an Instagram account? I somehow forgot the password. I love any assistance you can give me.
@Joseph Westin Thanks so much for your reply. I found the site thru google and im trying it out now. Seems to take quite some time so I will reply here later when my account password hopefully is recovered.
How can i calculate the new GM of the ship in a situation like this??Suppose i can find the FSC,can i connect it somehow and find the new GM OF THE vesel?
flaptsak87 GM (fluid)= GM (solid)- FSC & GM (solid)= KM- KG . We need to find KM and KG. These values are calculated using information from ship stability booklet. You can refer this video to find GM , that is GM (solid).ruclips.net/video/pPDzHoioYlY/видео.html&lc=z12ldh2hhuulvdcwy04cezhilqyaeh5znx00k
As long as there is sufficient liquid free to move across the breadth, there will be free surface effect. For a box shaped tank, if the space occupied ( or mass as mass= volume x density) by liquid is between 5% to 95% (approx ), the free surface effect is almost same and a constant value of FSC ( Free Surface Correction) is taken. However if the liquid filled in a tank is above 95 % ( less space to move), value of FSC reduces and can be neglected . For a triangular shaped tank, this effect is even more than box shaped vessel due to the large shift of center of gravity of liquid.
Dear friend, so called FSE is in fact transversal moment of inertia of free SURFACE and is not therefore connected in any way with volume of liquid in tank. In other words, it doesn't matter, if you have 1 meter, or 1 mm of free liquid in tank. Effect on GM will be the same. Basic formula of transversal moment of inertia for rectangular tanks is: lxb^4/12. Thus you can see, that there is no units used in the formula and you can see what factor (b^4) is contributing most to the detrimental effect of this phenomenon. I skip over mixing initial stability with GZ curve in view of the FSE. This is bad educational tool for our young officers.
Great explanation 🙌
Excellent video. Very useful. Thanks!
Thanks a lot, its a magnificent explanation about F.S.C and all points involving this condition.
Great, thanks for sharing!!!
Thanks for the video :-)
AGain, thank you my friend.
you have made my life so easy. thank you very much.

@Joseph Westin it did the trick and I now got access to my account again. Im so happy!
Thank you so much you saved my account !
@Titus Abdiel You are welcome :)
Very intersting demo☆☆☆
thanks good explanation
Thank you so much sir
👌👌👍👍
Thank u sir
Magnitude in. the formula should be b^3, sorry for that.
Good day i was expecting that you will give the formula off FSM=Gz x (displacement)
Thnq sir
😅can you give an example of free surface effect of triangular surface.

Captain Araine?
So the mass of the liquid in the tank has no effect on FSM and FSC?
As long as there is sufficient liquid free to move across the breadth, there will be free surface effect. For a box shaped tank, if the space occupied ( or mass as mass= volume x density) by liquid is between 5% to 95% (approx ), the free surface effect is almost same and a constant value of FSC ( Free Surface Correction) is taken.

SAILORSTUBE thx for the reply
small g is the weight of fluid?

Why "12" in the formula ?
