Formula to calculate the weight of the aluminum tube is:
Weight (W)
= [(π/4) x (OD² - ID²) x L] x Density of Aluminum(Varies Material to material)
Make sure to use consistent units (either millimeters or inches) throughout the calculation.
Here's a step-by-step example:
Let's assume:
OD = 50 mm
ID = 40 mm
L = 1000 mm (1 meter)
Density of Aluminum = 2.7 g/cm³
Step 1:
Calculate the cross-sectional area of the tube.
Area (A) = (π/4) x (OD² - ID²)
Area (A) = (3.1416/4) x (50² - 40²) mm²
Area (A) = 7850 mm²
Step 2:
Convert the cross-sectional area to square centimeters (cm²) for consistency with density units.
Area (A) = 7850 mm² = 7850/100 cm² = 78.5 cm²
Step 3:
Calculate the weight of the tube.
Weight (W) = Area (A) x L x Density of Aluminum
Weight (W) = 78.5 cm² x 1000 mm x 2.7 g/cm³
Weight (W) = 211950 g or approximately 211.95 kg
So, the weight of the aluminum tube in this example is approximately 211.95 kilograms.
