Pipe Surge and Water Hammer Apparatus

Code: C7MKII

The C7MKII demonstrates pipe surge and water hammer, phenomena which occur when fluid flowing in a pipe is accelerated or decelerated. As associated pressure transients can damage pipework, systems must be designed to avoid or withstand them.

Pipe Network Apparatus

The basic unit contains everything required to demonstrate the fundamental principles, but an accessory (C1-MkIII-30) is available containing a number of interchangeable test sections to give a wider knowledge and understanding to the student.

A further accessory (C1-MkIII-35) allows full compressor performance and characterisation tests to be carried out.
