The mass of the displaced fluid can be expressed in terms of the density and its volume, m = ρV. The fluid displaced has a weight W = mg, where g is acceleration due to gravity. Therefore, the weight of the displaced fluid can be expressed as W = ρVg .
Density (d) is calculated from the mass (m) and volume (V) of a substance by the formula: \[d = \frac{m}{V}\nonumber\] Mass is usually measured using an analytical balance. The volume of liquids can be measured using a graduated cylinder, pipet, or density bottle. The volume of regular solids can be calculated from the geometric parameters.
21 lis 2023 · This is how to calculate volume through water displacement. How do you calculate volume by water displacement? The volume of an irregular shaped object is typically calculated with...
Now use the following formula to calculate the volume of the object. Volume (object) = Volume (water + object) – Volume (water) Volume (object) = Vol2 – Vol1 Volume (object) = (30 – 13.33)
Sometimes you can figure out volume displaced by employing Archimedes' principle and/or static equilibrium. For example, suppose you have something floating on water, partially submerged. You know its weight, although maybe you don't know the volume submerged (which is the volume displaced).
In simple terms, the principle states that the buoyant force (F b) on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume (V) times the gravity (g)
