I have a huge tank full of water and a bar meter at its bottom shows presure 2 bars.
If we place a ship into the tank, are we going to have presure increase?

The bar meter is reading hydrostatic pressure, which is given by the equation:
P = density * height * acceleration of gravity

By putting a ship into the tank you will not change the density of the water ann you will not change the acceleration of gravity. What you will change is the height of the water column on top of the bar meter, hence the pressure reading should change too. If the tank is huge, as you said, then the change in height of the water column is minimum and the bar meter will seem to not record any change in pressure. The smaller the tank, the greater the change in the pressure reading.

At a pressure of 2 bar gauge, the water must be around 20m deep. (If it's 2 bar absolute, then the water is 10 m deep.
Either way, depending on the mass of the ship, the water level will rise accordingly by the ship's displacement.
For every metre increase in water level, the bottom pressure will show an increase of about 0.1 bar. Calculate from there.

Yes, the pressure will increase by the amount of the diaplacement of the ship, which is equal to it's weight.

The change in pressure times the area of the bottom of the tank will equal the weight of the ship.

Yes, of course. The ship will increase the level in the tank, which in turn causes the pressure at the bottom to increase. It happens to me when I get in the bathtub. You too?

The water will rise and there will be a minute increase in pressure

Yes. The water will rise and the pressure is an indication of how deep the water is.

No, we at the instant are not likely to have a upward push interior the stress on the backside of the tank. all of us understand that stress on the backside of a tank full of a liquid is given by skill of P=h*d*g, the place 'h' is the intensity of liquid, 'd' is density of liquid and 'g' is acceleration simply by gravity. as quickly as we place a deliver in water interior the tank, neither 'h' will replace (whether the load of the deliver is super, simply by fact water is incompressible) and nor will 'd' and 'g'. for this reason, stress on the backside of the tank will proceed to be the comparable.
