1. Calculation of Kinematic Viscosities:

For Test Temperature at 20°C

ν=ct

= 1037.6 × 0.247sec

= 256.2872mm²/sec

For Test Temperature at 40°C

ν=ct

= 365 × 0.247sec

= 90.1550 mm²/sec

2. Calculation of Dynamic Viscosities:

For Test Temperature at 20°C

ν= η/ρ

256.2872 =η 0.9977

η = 256.2872 x 0.9977

= 255.6977 mPa.S

For Test Temperature at 40°C

ν= η/ρ

90.1550 =η/ 0.9977

η = 90.1550 x 0.9977

= 89.9476 mPa.S
