CALCULATIONS:

                    ν=ct-----------------------------------------(i)

Where, ν= Kinematic viscosity

c= Viscometer constant

               t= time of flow in seconds (Redwood second)

 

For Redwood Viscometer- I, the values for the constants are as below:

 

Time of flow,t	C
40 to 85 seconds	0.264
85 to 2000	0.247

 

ν= η/ρ------------------------------ (ii)

 

Where, ν= Kinematic viscosity

              η= Dynamic viscosity

               ρ= Density of fluid

 

1.      Calculation of Kinematic Viscosities:

 

For Test Temperature at 20⁰C

               ν=ct

                = 0.264 x 60.05sec

                = 15.853mm²/sec

 

For Test Temperature at 40⁰C

ν=ct

               = 0.264 x 58sec

               = 15.312mm²/sec

 

2.      Calculation of Dynamic Viscosities:

 

For Test Temperature at 20⁰C

               ν= η/ρ

               15.9853= η/0.8429

               η =15.853 x 0.8429

                 = 13.362mPa.S

 

For Test Temperature at 40⁰C

               ν= η/ρ

               15.312= η/0.8429

               η = 15.312 x 0.8429

                 = 12.906mPa.S

Conclusions:

Kinematic viscosity (experimental) of test chemical at 20 Deg C and 40 Deg C is 15.853 mm2/sec and 15.312 mm2/sec, respectively.
Dynamic viscosity (calculated) of Aldehyde-C-11-Undecyclnic at 20 Deg C and 40 Deg C is 13.362 mPa.S and 12.906 mPa.S, respectively.
