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

               = 0.247×166.6 sec

                =  41.150 mm²/sec

 

For Test Temperature at 40⁰C

ν=ct

               = 0.247×115 sec

               = 28.405 mm²/s

 

2.      Calculation of Dynamic Viscosities:

 

For Test Temperature at 20⁰C

               ν= η/ρ

               41.150  =η/0.8859

               η = 41.150×0.8859

                 =36.45mPa.S

 

For Test Temperature at 40⁰C

               ν= η/ρ

               28.405 =η/0.8859

               η = 28.405×0.8859

                 = 25.16mPa.S

Conclusions:

Kinematic viscosity (experimental) of test material at 20 Deg C and 40 Deg C is 41.15 mm2/sec and 28.40mm2/s ,respectively.
