How do you find the volume of a submerged object?

The volume of water displaced Vw can be found by solving the equation for density ρ=mV ρ = m V for V.

How do you calculate pressure under water?

In the case of the water stored in a tank, the pressure at its bottom is the weight acting on a unit area of the surface where the tank is kept. To translate that into an equation: Pressure = weight/area, and weight = mass (m) * acceleration due to gravity (g). This means pressure = m * g/ area.

How do you find the pressure at the bottom of a container?

The pressure at the bottom of the container is therefore equal to atmospheric pressure added to the weight of the fluid divided by the area: p=p0+ρAhgA=p0+ρhg.

What is the pressure under water?

14.7 pounds per square inch
Pressure. The density of water causes ambient pressures that increase dramatically with depth. The atmospheric pressure at the surface is 14.7 pounds per square inch or around 100 kPa. A comparable hydrostatic pressure occurs at a depth of only 10 metres (33 ft) (9.8 metres (32 ft) for sea water).

Which principle is used for calculating the Centre of pressure?

We will use the concept of “principle of moments” to determine the centre of pressure. According to the principle of moments, moment of the resultant force about an axis will be equal to the sum of the moments of components about the same axis.

How do you find density with pressure and height?

P=hρg P = h ρ g , where P is the pressure, h is the height of the liquid, ρ is the density of the liquid, and g is the acceleration due to gravity.

What happens to air pressure as elevation increases?

As altitude rises, air pressure drops. In other words, if the indicated altitude is high, the air pressure is low. As altitude increases, the amount of gas molecules in the air decreases—the air becomes less dense than air nearer to sea level.

Why the center of pressure is not at the center of the body?

In general term, the center of pressure is located below centroid since pressure increase with depth. The determination of the center of pressure can be performed by equating the moments of the resultant and distributed forces about any arbitrary axis.
