1. Calculation of Kinematic Viscosities:

For Test Temperature at 20°C

ν=ct

= 174.3 × 0.247sec

= 43.0521mm²/sec

For Test Temperature at 40°C

ν=ct

= 142.3 × 0.247sec

= 35.1481 mm²/sec

2. Calculation of Dynamic Viscosities:

For Test Temperature at 20°C

ν= η/ρ

43.0521 =η 1.1029

η = 43.0521 x 1.1029

= 47.4821 mPa.S

For Test Temperature at 40°C

ν= η/ρ

35.1481 =η/ 1.1029

η = 35.1481 x 1.1029

= 38.7648 mPa.S

Conclusions:
Kinematic viscosity (experimental) of Reaction mass of Methylium, tris[4-​(diethylamino)​phenyl]​-​ & acetate at 20°C and 40°C was 43.0521 mm²/sec and 35.1481mm²/s,respectively.Dynamic viscosity (calculated) of Reaction mass of Methylium, tris[4-​(diethylamino)​phenyl]​-​ & acetate at 20°C and 40°C was 47.4821 mPa.S and 38.7648 mPa.S, respectively.
