 (1)60deg.Staggered | |
 (2)45deg.Staggered | |
 (3)Straight | |
 (4)Round End Slot Staggered OpenArea(%)=(2×W×L)-(0.43xW2)/2×SP×LP × 100 | |
 (5)Round End Slot Straight OpenArea(%)=(2×W×L)-(0.43×W2)/2×SP×LP × 100 | |
 (6)Square Staggered OpenArea(%)=W2/SP1×SP2 × 100 | |
 (7)Square Staggered OpenArea(%)=W2/SP1×SP2 × 100 | |
 (8)Hexagonal 60deg.Staggered OpenArea(%)=W2/P2 × 100 | |
 (9)Square End Slot Staggered OpenArea(%)=WxL/SP×LP × 100 | |
 (10)Square End Slot Straight OpenArea(%)=WxL/SP×LP × 100 | |
