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 at20⁰C

               ν=ct

                = 0.264x50.3sec

                = 13.27mm²/sec

 

For Test Temperature at 40⁰C

ν=ct

                 = 0.264x 46.3sec

                 =12.22mm²/s

 

2.      Calculation of Dynamic Viscosities:

 

For Test Temperature at20⁰C

               ν= η/ρ

               13.27 = η/0.7583

               η = 13.27 x 0.7583

                 = 10.06mPa.S

 

For Test Temperature at 40⁰C

               ν= η/ρ

               12.22 = η/0.7583

               η = 12.22 x 0.7583

                 = 9.26mPa.S
