1. Calculation of Kinematic Viscosities:

For Test Temperature at 20°C

ν=ct

= 623.6 × 0.247sec

= 154.0292mm²/sec

For Test Temperature at 40°C

ν=ct

= 216 × 0.247sec

= 53.3520 mm²/sec

2. Calculation of Dynamic Viscosities:

For Test Temperature at 20°C

ν= η/ρ

154.0292 =η 1.1201

η = 154.0292 x 1.1201

= 172.5281 mPa.S

For Test Temperature at 40°C

ν= η/ρ

53.3520 =η/ 1.1201

η = 53.3520 x 1.1201

= 59.7595 mPa.S
