WebbFlowmeters are devices that measure the amount of liquid, gas or vapor that passes through them. Some flowmeters measure flow as the amount of fluid passing through the flowmeter during a time period (such as 100 liters per minute). Other flowmeters measure the totalized amount of fluid that has passed through the flowmeter (such as 100 liters). WebbLh/D is a function of Re. Lh Fully Developed Pipe Flow Comparison of laminar and turbulent flow There are some major differences between laminar and turbulent fully developed pipe flows Laminar Can solve exactly (Chapter 9) Flow is steady Velocity profile is parabolic Pipe roughness not important It turns out that Vavg = 1/2Umax and u(r)= 2Vavg(1 - …
Webbthe flow velocity in high-grit sewage handling systems should not exceed 12 ft/sec. the flow velocity in sewage systems with low grit concentrations should not exceed 18 ft/sec.

Webb1.3 Laminar Pipe Flow Laminar flow through a circular pipe is called Poiseuille2 flow or Hagen3-Poiseuille flow. In laminar flow the shear stress is related to the velocity gradient: 𝜏= d d (8) Hence, from (6) and (8), d d =− 1 2 Integrating and applying the no-slip condition at the wall ( =0 on = ), Laminar pipe-flow velocity profile = 4

To reduce the velocity, a reducer pipe or a pipe valve can be used. Reducer pipes are often used because of the costly nature of pipe valves. These reducer pipes, which are larger in diameter, help to disperse the flow, therefore reducing the velocity.
