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.
