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 20°C

ν=ct

= 210 × 0.247sec

= 51.8700mm²/sec

For Test Temperature at 40°C

ν=ct

= 191 × 0.247sec

= 47.1770 mm²/sec

2. Calculation of Dynamic Viscosities:

For Test Temperature at 20°C

ν= η/ρ

51.8700 =η 1.1013

η = 51.8700 x 1.1013

= 57.1244 mPa.S

For Test Temperature at 40°C

ν= η/ρ

47.1770 =η/ 1.1013

η = 47.1770 x 1.1013

= 51.9560 mPa.S
