1. Calculation of Kinematic Viscosities:

For Test Temperature at 20°C

ν=ct

= 732 × 0.247sec

= 180.8040mm²/sec

For Test Temperature at 40°C

ν=ct

= 190 × 0.247sec

= 46.9300 mm²/sec

2. Calculation of Dynamic Viscosities:

For Test Temperature at 20°C

ν= η/ρ

180.8040 =η 0.9728

η = 180.8040 x 0.9728

= 175.8861 mPa.S

For Test Temperature at 40°C

ν= η/ρ

46.9300 =η/ 0.9728

η = 46.9300 x 0.9728

= 45.6535 mPa.S

Conclusions:
Kinematic viscosity (experimental) of Tributylmethylammonium chloride (CAS No. 56375-79-2) at 20°C and 40°C is 180.8040 mm²/sec and 46.9300 mm²/s,respectively.
