=π × L × D2/4-π×L×(D2+d2+D×d))/12
To instead release:
L=12 × (grinding air amount of storage at fine angle)/(3 × π × D2-π×(D2+d2+D×d))。
Step 2: angular range is calculated, tan α=(D-d)/2/L, α=arctan ((D-d)/2/L)
The air amount of storage such as at selection d=0.01, D=0.1257, pre-buried fibre angle: 0.00009 cubic millimeter, then may be used
To obtain,
L=12 × 0.00009/ (3 × π × D2-π×(D2+d2+ D × d))=0.01137
α=arctan ((D-d)/2/L)=arctan ((0.1257-0.01)/2/0.1137)=79 °.
