HF 160 WATER HAMMER APPARATUS
GENERAL DESCRIPTION

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). A Hydraulics Bench (required but separately supplied) with a measuring tank, a storage tank and a pump is used for both water supply and flow rate, measurement.

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.
