Practical Example

Let’s say you’re designing an exhaust system and want to calculate the total port area for four circular ports with a diameter of 60 mm each.

1. Select Circle as the shape.
2. Enter 60 mm in the diameter field.
3. Input 4 as the number of ports.
4. Click Calculate.

The calculator will apply the formula: Area=π×(Diameter2)2\text{Area} = \pi \times \left(\frac{\text{Diameter}}{2}\right)^2Area=π×(2Diameter​)2 Area=π×(30)2=2827.43 mm2\text{Area} = \pi \times (30)^2 = 2827.43 \, mm^2Area=π×(30)2=2827.43mm2

• Single Port Area: 2827.43 mm²
• Total Port Area (4 ports): 11,309.73 mm²

This quick result helps you immediately understand how much area your design accommodates.
