Head Loss Study Unit

HEAD LOSS STUDY UNIT -SELF-SUFFICIENT

With this unit, friction head losses in straight pipes of very different sizes can be investigated ise over a range of Reynolds numbers from 103 to nearly 105. This covers the laminar, transitional and turbulent flow regimes in smooth pipes.
