Poiseuille′s Equation
- The volume flow rate of an incompressible fluid in a round pipe is given by:
- where
- Q = volume flow rate [m3s-1]
- r = radius of pipe [m]
- p1-p2 = pressure difference between points 1 and 2 [Nm-2]
- μ = dynamic viscosity of fluid [Nsm-2]
- L = distance between points 1 and 2 [m]
- r = radius of pipe [m]
