Question

Write notes on Density and pressure of water
​

Answer 1

Density is the mass per unit volume of a substance or object, defined as ρ=m/V. ρ = m / V . The SI unit of density is kg/m3. kg/m 3 . Pressure is the force per unit perpendicular area over which the force is applied, p=F/A.

Pressure and Density Relationship

When density increases, pressure increases. When density decreases, the pressure decreases.

Since the density is constant, the weight can be calculated using the density: w=mg=ρVg=ρAhg. 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.
