ok, ona wygląda jak kurwa, ale cycki ma niezłe, racja?
:D

I am afraid that it is impossible to write a programme that translates ideally...
have a look at this example:

'I love dorota rabczewska'
'kocham dorotę rabczewską'


in polish, and quite a lot of other languages, you can sometimes omit nouns because each verb has a different inflection (indicating the person). So thx to the context you can guess the meaning anyway.
Saxon genitive ' 's ' is probably the only thing in English that works in the way inflections work in other languages

What is more, thx to inflections you can have almost any word order you want.

here are a couple of sentences that have the same meaning as 'I love Dorota Rabczewska':

'Kocham Dorote Rabczewską'
'Ja kocham Dorotę Rabczewską'
'Dorotę Rabczewską kocham ja'
'Dorotę Rabczewską ja kocham'
'Dorotę rabczewską kocham'


All of them are perfectly correct, though the first and the second one is most often used

Nie powiedziałem, że fakt, że wygląda jak kurwa jest złe :D

Only on spudfiles would a discussion about maximum blowgun pressure could we degenerate into the grammatical correctness of expressing one's affection for a woman of poor virtue in Polish :roll: :D

I love this forum :D

ohh yeah it seems you're right... care to elaborate on this
The static pressure will be higher than the dynamic pressure, but i doubt that you care about anything other than the dynamic pressure
??

:wink:
Static pressure would be the pressure eld by a closed valve.
Dynamic pressure would be the pressure held if the valve was being opened and closed. When the valve is being operated at high pressures the seals are more likely to become damaged from high velocity airflow.

do you have some links on it ?

dynamic vs. static pressure was mentioned only by someone explaining the Bernoulli's principle... I couldn't find anything about seals

there is a lot about dynamic vs. static seals though, but that's probably not the same thing as dynamic vs. static pressure

I do not have any literature confirming what I said. It was just common sense to me to say that static pressure would be higher than dynamic, however static pressure would'nt help much because you will be openig and closing the valve.

hmm... I found some info on it but the term dynamic pressure refers to airfoils mostly... it seems that this thing does not apply here, though I might be wrong

forget that I ever said anything about dynamic pressure
I am begining to think that that was wrong.
however it does make sense that the valve could withstand more pressure if the valve was not being opend and closed
