The sheets to be hot-glued to the front-cover and cardboard backing. The pad should contain sheets of a minimum of 5 different strong colors.
Paper pad, 50 sheets A4-sized (297 x 210 mm) plain (un-ruled) colored sheets, hot-glued on the 210 mm side, with front-cover and cardboard backing.
Sheets to be of 75% recovered paper fibres (post and pre-consumer waste), 80 gsm with a cardboard backing sheet of approximately 600 gsm, and a front covering sheet of approximately 160 gsm.
Recycled paper
The composition of the paper should be homogenous with no
inclusions/alien particles and be suitable for a range of art activities # painting, coloring, sticking etc.
The paper should be easily removed from the pad.
The composition of the paper, design and the method of attachment must be suitable for the safe and extended use by children.
Recycled paper
Paper: 75% recovered paper fibres (post and pre-consumer waste) non coated 110 GSM. The composition of the paper should be homogenous with no inclusions/alien particles or wrinkles.
Cover: There is no cover sheet on the front of the pad.
Finishing: Top glue along the 297 mm side, using an A3 size piece of cardboard, 600 GSM, attached to the back of the pad. Trim to size.
Size: A3 (420 mm long x 297 mm wide).
Pages: 48 sheets
Printing: no printing.
A set of thirteen graduated tubes show the oil pressure across and along the film under the pad. The bench-mounting unit has an aluminium plate (pad) mounted above a continuous loop flat belt. This creates a pressurised film of oil between the pad and the belt. The belt runs in an oil reservoir to provide a continuous supply of oil under the pad.
Students vary the belt speed to find the relationship between sliding speed, oil viscosity and pressure distribution. Included is a variable speed control to control the speed of the motor that turns the belt.
Experiments:
Pressure distributions in a tilting pad bearing.
The relationship between pressure and the film thickness at the trailing edge of the pad.
Influence of sliding speed and viscosity on the pressure distribution in the bearing and comparison with calculations based on Reynolds equation.
Non-contact recording of rotation speed by ring magnet and Hall sensor
Display indicating flow rate
Paddle wheel flow meter as accessory for trainer
Vertical and horizontal installation possible
Connections to supply auxiliary power via
Connections to facilitate pressure loss measurement.
