![]() Note: You can enter whatever variables you know, and the calculator will compute the rest. Assuming that (x) is an integrable function, the mass of the rod is given by the integral. The density of the rod at any point x is defined by the density function (x). Consider a thin wire or rod that is located on an interval a, b. The calculator will display the volume of the fluid displaced (2030 cm 3) and the buoyant force (19.89 N). We can use integration for calculating mass based on a density function. The mass calculator finds the mass of an object using the given values. If the height of the water inside the container changes by 2.86 cm, we can calculate the buoyant force as:Ĭlick on the Advanced mode button beneath the calculator and type the change in the height of the fluid (2.9 cm) and surface area of the fluid (700 cm 2).Įnter the true mass of the object (5 kg). Enter the values of density and volume below using which you want to find the mass. Let us consider another example, where we drop a 5 kg rock into a cylindrical container with a base surface area of 700 cm 2. It will also show the buoyant force acting on the rock as 1.96 N and a message whether the rock will float or sink. Find the total mass of a 1-m rod whoselinear density function is p(x). The Archimedes' principle calculator will display the density of the rock as 2.70 g/cm 3 and the volume of the rock as 200 cm 3. Calculate the volume of the ramp in Figure 2 in three ways by integrating the area. You can also enter the density of the fluid manually. Using the drop-down menu, choose fluid type as water. We will calculate the average density of this rock as follows:Įnter the true mass and the apparent mass of the rock as 540 g and 340 g in the respective fields. ![]() Finally, if the region E E can be defined as the region under the function z f (x,y) z f ( x, y) and above the region D D in xy x y -plane then, Volume of E D f (x,y) dA Volume of E D f ( x, y. As the volume increases, the density decreases. Does more volume mean more density Volume and density are inversely related. What is the unit of density Density is measured in kg/m units. Let the true mass (mass in the air) and apparent mass (when immersed in water) of a rock be 540 g and 340 g, respectively. First the volume of the region E E is given by, Volume of E E dV Volume of E E d V. To calculate the density use the formula m/V, where m is the mass and V is the volume. In this section, we will try to determine the density of an unknown object using our Archimedes' principle calculator. ![]()
