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

= 1680 × 0.247sec

= 414.9600mm²/sec

 

For Test Temperature at 40°C

ν=ct

= 1440 × 0.247sec

= 355.6800 mm²/sec

 

2. Calculation of Dynamic Viscosities:

For Test Temperature at 20°C

ν= η/ρ

414.9600 =η 0.9777

η = 414.9600 x 0.9777

= 405.7063 mPa.S

 

For Test Temperature at 40°C

ν= η/ρ

355.6800 =η/ 0.9777

η = 355.6800 x 0.9777

= 347.7483 mPa.S
