Density Equation for Cylinder:
| From: | To: |
Density is a measure of mass per unit volume. For a cylinder, it's calculated by dividing the mass of the cylinder by its volume. This calculator helps determine the density of cylindrical objects using their mass, radius, and height.
The calculator uses the density equation for a cylinder:
Where:
Explanation: The equation calculates the volume of the cylinder first (πr²h) and then divides the mass by this volume to get density.
Details: Density is a fundamental property of materials used in physics, engineering, and materials science. It helps identify substances, determine buoyancy, and is crucial in many industrial processes.
Tips: Enter mass in kilograms, radius and height in meters. All values must be positive numbers. For best accuracy, measure dimensions precisely.
Q1: What units should I use for the inputs?
A: The calculator expects mass in kilograms (kg) and dimensions in meters (m) for density in kg/m³. You can convert from other units before entering values.
Q2: Does this work for hollow cylinders?
A: No, this calculates density for solid cylinders. For hollow cylinders, you need to account for the empty space in volume calculation.
Q3: What's a typical density range for common materials?
A: Metals range from 2700 kg/m³ (aluminum) to 7870 kg/m³ (steel). Water is 1000 kg/m³, plastics range from 900-1400 kg/m³.
Q4: How precise should my measurements be?
A: For scientific purposes, measure to at least 3 significant figures. For general purposes, 2 decimal places is usually sufficient.
Q5: Can I use this for liquids in cylindrical containers?
A: Yes, if you measure the mass of just the liquid and use the interior dimensions of the container for volume.
