Method:
1. 1. Measure the diameter ofthe loose bead using the micrometer.
2. 2. Measure the weight of theloose bead using the electronic scale.
3. 3. Measure the weight of themeasuring cylinder.
4. 4. Fill one of the measuringcylinders (A), (B) or (C) with 100 ml of engine oil.
5. 5. Measure the weight ofthat measuring cylinder and the oil it contains.
6. 6. Fill each of themeasuring cylinders (A), (B) and (C) with more than 100 ml ofengine oil by about 20ml.
7. 7. Set the refrigerator at atemperature of 15°C, then place measuring cylinder (A)into it for half an hour or so to get it to the temperatureneeded. After that remove measuring cylinder (A) fromrefrigerator.
8. 8. Instantly place the loosebead into measuring cylinder (A). Then measure the time it takesthe loose bead to travel the distance between 75 ml to 25 mlmarkings on the cylinder. Record your results in a table.
