Water Hammer Apparatus

Water Hammer Apparatus. This apparatus is used to study the effects of both pipe surge and water hammer using two separate straight pipes with a constant head tank.

Pipe surge employs a clear acrylic surge shaft to demonstrate gradual velocity change, hence pressure rise and its oscillations by slow valve closing. Water hammer employs a quick closing valve and two pressure sensors-one next to the valve and another further away. Sudden rise in pressure on quick closing valve can be demonstrated on a computer (separately supplied). The equipment is to be used with Hydraulics Bench (separately supplied).

Instruction manual is also included.
