Low pressure pipe flow facility

A pipe flow facility designed for use under low pressure.  A  "relaxation"-section for pressure recovery, with a connection to a vacuum-tank and a pump placed in the basement to prevent pump-cavitation are the specific features of this set-up. This in combination with the fact that all pipe and hose connections are air-closed.

The inner diameter of the main part of the pipe is 50mm, the pipe-material is perspex.
