Hi all,

I have a similar question.I only want to know calculation in a simple way for a G 6 Building with the stairhall 3MX3Mx21.5M High. Can any one help me in calculating the air quantity of the blower needed to circulate air downwards to maintain the necessary pressure in an unfortunate case of the building in "fire".Thanks... my e mail ID is [email protected] in case some good person is willing to help me out... may GOD bless you.
