Bypass pipes, accompanied by a three-way control valve, are often seen in hydronic systems at both served loads (e.g., reheat coils) as well as at primary equipment (e.g., cooling towers). Reasons for ...

Ordinarily, if you want liquid to flow in only one direction through a pipe, that pipe needs to be equipped with a flap-type valve – which could fail. Now, however, scientists have created a new type ...

"We found that sipping through a straw defies all the previously known laws for the resistance or friction of flow through a pipe or tube," explains Leif Ristroph, an associate professor at New York ...

If one looks at many practical fluid flows, either around bodies (flow of air over an airplane wing) or through conduits, (flow through pipes), the problem of turbulence presents itself in almost ...
