3. Digital Timing &
Photo-Gate Arrangement
The system incorporates a digital
timer with two photo-gate units and a dedicated arrangement for
holding the photo gates. This allows the timing portion of the experiment to be
carried out using an electronic sensing arrangement rather than relying only on
manual timing.
4. Experimental Configuration
The illustrated apparatus comprises:
- Vertical liquid-filled
experimental tube/viscosity apparatus.
- Supporting frame and stable base.
- Adjustable
photo-gate mounting arrangement.
- Two photo-gate sensing units.
- Digital timer/control unit.
- Steel balls of different sizes.
- Measuring
accessories.
- Glass funnel for liquid handling.
The supplied page image shows the viscosity apparatus and
digital timing arrangement as the principal experimental setup.
5. Educational Applications
The apparatus is intended for laboratory instruction
involving:
- Determination
of coefficient of viscosity.
- Stokes’
method of viscosity measurement.
- Study using glycerine or castor oil
as the experimental liquid.
- Measurement of the time taken by
steel balls during their motion through the liquid.
- Comparison of results using steel
balls of different sizes.
6. Key Features
- Dedicated
apparatus for Stokes’
method.
- Suitable for
glycerine or castor oil.
- Steel balls
of different sizes supplied.
- 20 × 1 mm screw gauge included.
- Digital
timing facility.
- Two
photo-gate units.
