What is the unit "pt/min" ?
and how can I convert it to Liters/sec or kg/s or any other unit?
I see it in some documents, but I can't find its conversion by searching in google.
Please use the unit in some context. I have not seen this. It could be pint per minute. If scanning inputs, it could be point per minute. In a really wild guess it could also be some abreviation like platinum minimum.
Here is a Timken reference to lubricant flow rate used in their bearing load determinations. Apparently Timken uses L/min or pt/min. You learn something everyday.
