airflow - perforated steel
(OP)
Can anybody help me predict the pressure drop/airflow through a perforated steel plate? My application is ~6000cfm with an opening of ~4000in2 with ~58% open area. I would like to calculate the effect of changing the % open area or opening size.

ASHRAE has a pretty reliable and user-friendly equation to work with for air:
Q = 2,610 * A * dP^.5
Q = flow in cfm
A = net open (or orifice) area in square feet
dP = pressure difference driving (or resulting from) flow, in inches of water

appreciate if you be more specific on the equation,
Q = 2,610 * A * dP^.5
Q = flow in cfm
A = net open (or orifice) area in square feet
dP = pressure difference driving (or resulting from) flow, in inches of water
i need to size the perforated floor board enough air circulation for the server rack.
thanks.
