Hi.

That's right!

but as you're a numb, and allow me the provocation, very unprofessional. . .

I'm sorry, you know, if we were trying to make you realize that some "problems" can be solved by themselves... You're obviously used to finding the ready pipe.
better for you.. I hope you always have this luck.

if you want answers ready and complete you have to contact a paid service.
here each user helps a colleague if he wants it and if he has a specific computation on the subject.
to answer your question you have to do a google search, find a table and copy the data here on the forum.
It is an alvour that does not require any particular competence but a discrete loss of time (not paid) and so you can do well alone. That's what you got.

 

[Ilario]

exhausted argument and given and exhaustive answers, if you can't read or use google... I'm sorry for you....

Lock and stop.
