ACTUALLY MAN HS INVENTED SUBMARINE BY STUDYING THE FLOATATION OF FISHES
BASICALLY IT CONSISTS OF 3 VITAL COMPARTMENTS
1)ENGINE ROOM
2)BALLAST TANK
3)COMPRESSED AIR COMPARTMENT(C.A.C)
IN ADDITION TO THIS THERE IS A CONTROL & ROOMS FOR THE MEMBERS.
UNDER NORMAL CONDITIOND ,IT IS AN AIR TIGHT SHIP.
IT DISPLACES MORE WT. WATER THAN IT'S OWN WT.
HENCE IT FLOATS ON TH SURFACE OF WATER.
IT'S BALLAST TANK IS EMPTY & THE C.A.C CONTAINS HUGE STEEL CYLINDERS OF AIR AT 100 ATM.PRESSURE
IN ORDER TO DIVE IN THE DOORS OF THE BALLAST TAN K ARE OPENED DUE TO WHICH THE WATER GUSHES IN.
AND INCREASES THE WT.OF SUBMARINE.AND THUS IT SAFELY SINKS IN WATER.
IN ORDER TO COME BACK TO THE SURFACE OF WATER,THE C.A.C. IS ALLOWED INTO THEW BALLAST TANK.
HENCE IT BECOMES LIGHTER AND COMES UP TO THE SURFACE OF WATER.
THUS THE SYSYEM IS ENTIRELY BASED ON LAW OF FLOATATION.

Submarines are built with the construction of ballast tanks which are filled with air initially . when the submarine floats on the sea water , the ballast tanks are filled with air . Hence , the density of the submarine remains less than that of the water . when the submarine should be sunk , the ballast tanks are filled with water . With the amount of water regulation , the depth to which the submarines have to be sunk can be controlled . Again when submarine should be made to float , the water from the ballast tanks is released . This the principle of the floatation and sinking of the submarines .

in the construction of a submarine,an entire portion is left free.when the submarine wants to sink,this room evacuate,as a result of the weight of the submarine ,it sinks down.but when it wants to float,this room is completely filled with air that provides an extra bouyant force along with that produces by water,the combined effect of these two upthrusts,the submarine is lifted up and hence it floats.

Subs have ballast tanks, true, straight up with air, straight down with no air. But subs can also fly in the water if under power. Neutral works on the water or below. Makes the sub able to change course in 3 d. rapidly.

due to ballast - when it pressurizes air in its tanks it floats -
and when the air is replaced with water -
we are going DOWN !!!!!
best of luck!

it has to do with water in take to sink and air pushing the water out to rise.
