Whirling of Shafts Apparatus
For studying the critical rotational speeds on simply loaded of various shafts. It is a self-contained bench mounting. Apparatus includes a DC motor drives the shaft via a flexible coupling. Motor speed can be continuously variable and displayed on a digital readout by a revolution counter. A transparent protective cover and safety rings ensure safe operation. The unit includes the tools need for easy experiment setup.

Hydraulic Studies and AccessoriesOsborne Reynolds Apparatus: Horizontal Test Pipe
This equipment provides laminar, transitional, and turbulent flow as predicted by Osborne Reynolds. It is to be used with Hydraulics Bench i.e. HB100 or HB100N (separately supplied).
It consists of a removable clear acrylic tank which is partitioned in half. Water is admitted at the bottom of one half through a diffuser and stilling material. The other half of the tank has an adjustable over flow pipe with a discharge at the bottom. Water from the tank is admitted into a clear horizontal shell inside which is a bell entry with a test pipe. Flow through the test pipe is controlled by a discharge valve. A dye injection system needle discharges the dye to the bell mouth and flow pattern in the test pipe can be observed.
TYPICAL EXPERIMENTS- Visualization of laminar, transition and turbulent flow
- Determination of the critical Reynolds number

Flow Measurement and Flow StudyWater 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.
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.
