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
Ink	110.38	0.00100	The viscocity is standard for water at 20°C
R11	N/A	0.80640	(Based on information from manufacturer)
Sugar - White (40tsp)	281.05		(Based on two readings only)
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
