Remarks on result:
other: calculated using density at 20°C

Batch 504, 20°C, k = 0.01011 mm²/s²

1. Run         390.34 s

2. Run         388.77 s

3. Run         390.45 s

Mean Value 389.85 s

with standard deviation 389.85 s+/- 0.94 s

Viscosity: 389.85 s x 0.01011 mm²/s² = 3.94 mm²/s

 

Batch 504, 40°C, k = 0.004847 mm²/s² 

1. Run         527.11 s

2. Run         527.17 s

3. Run         526.60 s

Mean Value 526.96 s

with standard deviation 526.96 s +/- 0.31 s

Viscosity: 526.96 s x 0.004847 mm²/s² = 2.55 mm²/s

Conclusions:
The kinematic viscosity has been determined to be 3.94 mm²/s at 20°C and 2.55 mm²/s at 40°C.
