The formula for calculating pressure in fluids is P = F/A, where P is pressure, F is force, and A is area.
The buoyant force in a fluid can be calculated using the formula Fb = Vρg, where Fb is the buoyant force, V is the volume of the displaced fluid, ρ is the density of the fluid, and g is the acceleration due to gravity.
Density is a measure of how much mass is contained in a given volume of a substance, while specific gravity is the ratio of the density of a substance to the density of a reference substance (usually water).
As temperature increases, the density of fluids decreases, as the molecules have more energy and move farther apart. On the other hand, as pressure increases, the density of fluids also increases, as the molecules are squeezed closer together.
To convert between units of measurement for fluid properties, you can use conversion factors such as 1 atm = 101.325 kPa or 1 lb/ft^3 = 16.018 kg/m^3. It is important to pay attention to the units when performing conversions to ensure accurate results.
