1. Calculation of Kinematic Viscosities:
For Test Temperatureat 200C
ν=ct
= 0.264 ×41 sec
=10.82mm2/sec
For Test Temperature at 400C
ν=ct
= 0.264 ×38 sec
=10.03mm2/sec
2. Calculation of Dynamic Viscosities:
For Test Temperature at 200C
ν= η/ρ
10.82=η/0.8676
η = 10.82 X0.8676
= 9.38mPa.S
For Test Temperature at 400C
ν= η/ρ
10.03 =η/0.8676
η =10.03X0.8676
=8.70mPa.S
