Poiseuille's Formula

The volume flow discharged through a smooth-walled circular pipe

The Poiseuille's formula express the disharged streamlined volume flow through a smooth-walled circular pipe:

V = π p r4 / 8 η l                        (1)

where 

V = discharge volume flow (m3/s)

p = pressure difference between the ends of the pipe (N/m2, Pa)

r = internal radius of pipe (m)

l = length of pipe (m)

η = viscosity of fluid
