1. Calculation of Kinematic Viscosities:
For Test Temperature at 40°C
ν=ct
= 1020.6 × 0.247sec
= 252.0882mm²/sec
For Test Temperature at 60°C
ν=ct
= 985.3 × 0.247sec
= 243.3691 mm²/sec
2. Calculation of Dynamic Viscosities:
For Test Temperature at 40°C
ν= η/ρ
252.0882 =η 0.9787
η = 252.0882 x 0.9787
= 246.7187 mPa.S
For Test Temperature at 60°C
ν= η/ρ
243.3691 =η/ 0.9787
η = 243.3691 x 0.9787
= 238.1853 mPa.S
