ok I have the equation V = [(P1-P2)(pi*r^4)]/(8*n*L)

(P1-P2)= pressure difference

r= .000125 m

n= .0010055

L= .032 m

I do not know how I am suppose to transform 1.5g/s to m/s because im unsure of how to transfer grams to meters.... once i get that I can find the difference in pressure...

In a similar problem with diameter being .28mm the answer came out to be 320kPa... help???
