'''Pipe flow''', a branch of hydraulics and fluid mechanics, is a type of liquid flow within a closed conduit (conduit in the sense of a means of containment). The other type of flow within a conduit is open channel flow. These two types of flow are similar in many ways, but differ in one important aspect. '''Pipe flow''' does not have a free surface which is found in [[Open Channel Flow]]. '''Pipe flow''', being confined within closed conduit, does not exert direct atmospheric pressure, but does exert hydraulic pressure on the conduit.

Not all flow within a closed conduit is considered as '''Pipe flow'''. Storm sewers are closed conduits but usually maintain a free surface and therefore are considered as [[Open Channel Flow]]. The exception to this is when a storm sewer operates at full capacity, and then can become [[Pipe flow]].

Energy in pipe flow is expressed as head and is defined by the [[Bernoulli's Equation]]. In order to conceptualize head along the course of flow within a pipe, diagrams often contain a hydraulic grade line. '''Pipe flow''' is subject to frictional losses as defined by the [[Darcy-Weisbach Equation]].
