Swept Volume

Swept volume is the volume swept by a compressor piston during a complete stroke. Swept volume is expressed in cubic inches and calculated as follows:
Head End = Area Piston (in
2
) * Stroke (in)
Crank End = (Area Piston (in
2
) - Area Rod (in
2
)) * Stroke (in)
Total = [2 x Area Piston (in
2
) - Area Rod (in
2
) ] * Stroke (in)
