What does lead time mean?
Thread Content
To prevent any aqueous phase from being discharged along with the naphtha, a fixed funnel is installed in the naphtha chamber to provide approximately five minutes of lead time. To prevent the water phase from flowing out together with the naphtha, a fixed funnel is placed in the naphtha chamber to offer about 5 minutes of advance time. It doesn’t seem right; please help to take a look.
It seems that lead time is a common term in trade.
Given that there is no preposition after “provide 5 minutes”, it is guessed that “lead” might be an adjective meaning ‘main’. But it doesn’t seem to make sense in that context; translating it as \"guidance\" seems to give it some meaning after all
I guess it refers to lead time – it’s similar to the lead time commonly used in production (the total manufacturing time) and in economics (a concept often used in modern logistics, referring to the cycle from when an order is placed until the goods are delivered)
This post was last edited by AliceMa on 2009-8-31 at 17:27. After checking, it seems to refer to the lead time, that is, the time required in advance. Lead time is the period of time between the initiation of any production process and the completion of that process.
In trade, LEAD TIME should refer to the delivery time, right?
lead time= retention time
lead time n. the time between the initiation and completion of a production process. Production time–in this context, it refers to the time it takes for the aqueous phase and the oily phase to settle in a separatory funnel. ----------------------FYI
Time from order placement to delivery, used in engineering.
A fixed funnel is installed in the naphtha chamber to provide approximately five minutes of lead time. A fixed overflow weir is installed in the naphtha “intermediate tank”; this weir ensures that the “aqueous phase” has a five-minute “residence time”. ----The parts in quotes are paraphrased or added; they can be adjusted according to the context.
It seems that there are two views at present: one is that this term is a trade term, and the other is that it is a production term. I lean toward the latter.
