Viscosity Invistagation


What does viscosity mean

Viscosity is a measure of a fluid's resistance to flow. It describes the internal friction of a moving fluid. A fluidwith large viscosity resists motion because its molecular makeup gives it a lot of internal friction.

what you need

1. Measure out 30mls of each liquid

2. Set your stop watch to zero

3. Tip one liquid at a time from the top of the ramp. Remember to communicate with your group to ensure the timer starts as you tip the liquid.

4. Let the liquid flow for the set of time you have decided and measure the distance travelled

5. Record your results in the table

6. Repeat for each type of liquid , recording as you go

7. Clean your ramp for the next test

8. Tip one liquid down the ramp and time how long it takes to reach the bottom.

9. Record your results on the table

10.Repeat for each type of liquid recording as you go

11. Record each groups results as they become available.

12.Using a calculator , determine the mean distance and speed for each liquid
