Centreline velocity in pipes -- CFD Online Discussion Forums

Center-line velocity is usually the maximum velocity in the pipe, so it is, most of the time, larger than the average velocity. Average velocity is easy to calculate: so if you know the mass flow rate , the density , and the pipe cross-sectional area , you can calculate what the average velocity is.

Headloss - Pipe pressure drop calculator: .au

Velocity is directly related to flow rate. The size (inside diameter) of the pipe: Smaller pipe causes a greater proportion of the water to be in contact with the pipe, which creates friction. Pipe size also affects velocity. Given a constant flow rate, decreasing pipe size increases the water’s velocity, which increases friction.
