How to Calculate Volume of Cylinder in SolidWorks?

Understanding Cylinder Volume Calculation in SolidWorks

To calculate the volume of a cylinder within SolidWorks, it’s essential to grasp the geometric parameters involved. A cylinder is defined by its circular base and height. The volume formula for a cylinder is expressed as V = πr²h, where ‘r’ is the radius of the base and ‘h’ is the height. Here’s a step-by-step guide to obtain this measurement using SolidWorks.

Step 1: Create the Cylinder Shape

Begin by launching SolidWorks and opening a new part document. Utilize the ‘Extruded Boss/Base’ feature to create your cylinder. Before you proceed, measure and note down the radius and height you wish to apply.

• Select the ‘Circle’ tool from the sketch toolbar.
• Draw a circle on the plane of your choice. Specify the diameter by entering the radius value, which is half the diameter.
• After sketching, choose ‘Extruded Boss/Base’ and input the height of your cylinder in the dialog box.

This action will transform your 2D sketch into a 3D cylinder.

Step 2: Accessing Volume Calculations

With the cylinder created, it’s time to calculate its volume.

1. Go to the Tools menu located at the top of the SolidWorks interface.
2. Navigate to Evaluate and select Mass Properties. A dialog box will appear showing various properties of the part.
3. In this dialog box, you will find the volume listed along with other parameters such as mass and surface area. The volume reflects the exact volume of your cylinder based on the dimensions you have provided.

Step 3: Confirming the Volume Calculation

Verification is crucial.

• Cross-check the volume calculated in SolidWorks using the formula V = πr²h. With the radius and height you initially input when creating the cylinder, compute the volume manually using a scientific calculator.
• This will allow you to confirm that the SolidWorks calculation aligns with theoretical expectations.

Advanced Considerations

For more complex cylindrical shapes, such as hollow cylinders or those with varying diameters, additional parameters come into play.

1. For a hollow cylinder, make sure to input both the inner radius (r) and outer radius (R) to calculate the volume using the formula: V = π(R² – r²)h.
2. For cylinders with varying dimensions, consider breaking down the shape into multiple simpler cylindrical sections, calculating the volume separately, and then summing those volumes.

FAQ
