Materials
The table below shows the times recorded during the viscosity measurements for the materials tested. Unless otherwise specified, the measurements are based on an average from five readings.
Material | t (s) [Ave.] | viscosity (Pa.s) |
Notes |
Water | 32.46 |
0.00354 |

Sugar - Brown (20tsp) |
57.60 | ||
Sugar - Brown (25tsp) |
65.84 | ||
Sugar - Brown (30tsp) | 67.98 | This is NOT an error in calculation! | |
Sugar - Brown (35tsp) | 67.88 | This is NOT an error in calculation! | |
Sugar - Brown (48tsp) | 106.80 | ||
Sugar - Brown (50tsp) | 110.84 | This is almost the same viscocity as the ink which is used in the cartriges |
