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.

TYPICAL EXPERIMENTS

Pipe surge and oscillations in surge shaft.
Friction loss between head tank and surge shaft.
Pressure profiles for water hammer and comparison with theoretical values.
Determination of the velocity of sound through a fluid in a pipe.
