WebNov 5, 2024 · Fluid statics is the physics of stationary fluids. Density is the mass per unit volume of a substance or object, defined as ρ = m V. The SI unit of density is kg/m 3. Pressure is the force per unit perpendicular area over which the force is applied, p = F A. The SI unit of pressure is the pascal: 1 Pa = 1 N/m 2.
