An air handling unit delivers 2009 litres/second. How do i find how many pascals this would be.?

is there a formula/ conversion

Answers:
Here,volume =2009 litres/sec.

Q=A*V
2009=A*V, WHERE AREA DEPENDS ON SHAPE OF A CONTAINER.
V=VELOCITY.

PRESSURE=SPECIFIC GRAVITY*HEAD.

SO, DIMENSIONS OF THE DUCT AND TYPE OF FLUID IS REQUIRED TO CONVERT IT INTO PASCALS AS PASCALS IS A UNIT OF PRESSURE.
u don't. a litre is a unit of volume, and pascal is a unit of pressure, they aren't the same thing at all
a direct conversion isnt possible. si units of pascal are kg m-1 s-2, and litres/second is m3 s-1. you need to know the pascal conversion factor for 'air' if this exists, which will combine its 1 dimensional mass
there is a formula pv= RT
if this is air , then I believe you would have been given values of R the molar gas constant and T might be the room temperature i.e 25 deg C or 298 K. then it would look like this
p=RT/v

but i am not so sure
Q=A*V
2009=A*V, WHERE AREA DEPENDS ON SHAPE OF A CONTAINER. V=VELOCITY.

PRESSURE=SPECIFIC GRAVITY*HEAD.

SO, DIMENSIONS OF THE DUCT AND TYPE OF FLUID IS REQUIRED TO CONVERT IT INTO PASCALS, AS PASCALS IS A UNIT OF PRESSURE BUT THIS IS NOT AN EXACT SCIENCE IT WOULD GO + OR - 15%
