Calculation method
Calculation method
Parallel cover strips
max(1,ceil((b-e)/(c-e)))
Cut length per strip (m)
a+f
Rolls with no strip joining
ceil(max(1,ceil((b-e)/(c-e)))/math.floor(d/(a+f)))

Assumptions & limits
Assumptions & limits
- Parallel full-length cover strips; roll must fit at least one strip, strip width >lap≥0. No curing process specification or protection performance assertion. Supported limits: All numeric inputs must be finite. Only the explicitly described mathematical scenario is supported.
