Calculation of Dynamic Viscosities:

 

For Test Temperature at 200C

               ν= η/ρ

               172.9 = η/0.9376

               η = 172.9 x 0.9376              

= 162.11mPa.S

 

For Test Temperature at 400C

               ν= η/ρ

               66.69= η/0.9376

               η = 66.69 x 0.9376

                 = 62.52mPa.S
