1. Calculation of Kinematic Viscosities:
For Test Temperature at 800C
ν=ct
= 0.247 x 300 sec
= 74.1mm2/sec
For Test Temperature at 1000C
ν=ct
= 0.247 x 121.5sec
= 30.01mm2/s
2. Calculation of Dynamic Viscosities:
For Test Temperature at 800C
ν= η/ρ
74.1 = η/ 0.9825
η = 74.1 x 0.9825
= 72.803mPa.S
For Test Temperature at 1000C
ν= η/ρ
30.01 = η/0.9825
η = 30.01 x 0.9825
= 29.48mPa.S
