ρ= Density of fluid
1. Calculation of Kinematic Viscosities:
For Test Temperature at 200C
ν=ct
= 0.264 x 57.5sec
= 15.18mm2/sec
For Test Temperature at 400C
ν=ct
= 0.264 x 56sec
= 14.784mm2/s
2. Calculation of Dynamic Viscosities:
For Test Temperature at 200C
ν= η/ρ
15.18= η/ 1.0603
η = 15.18 x 1.0603
= 16.095mPa.S
For Test Temperature at 400C
ν= η/ρ
14.784= η/1.0603
η = 14.784 x 1.0603
= 15.675mPa.S
