Reference
Viscosity test was conducted for[4-[[4-(dimethylamino)phenyl][4-(methylamino)phenyl]methylene]cyclohexa-2,5-dien-1-ylidene]dimethylammonium acetate; CAS No. 84434-47-9.The Test item is a greenish lustrous liquid. (color and form of the chemical). To perform the test, the oil cup was cleaned with the tissue paper and kept on the viscometer’s stand. The water bath is filled with water and the oil cup with the Test itemafter placing the ball (valve) in the right position. A clean and dry 50 ml Kohlrausch flask was placed in such a way that the flask’s mouth was in the centre of the orifice jet of oil cup. The flow of Test item was observed at 30°C and then at 50°C. To count the flow time, the ball was lifted slowly and at the same time stopwatch was started. The oil was allowed to collect in the receiving flask. As soon as the oil touches the 50 ml mark of the flask, stop the watch was stopped and the time was recorded in seconds. The experiment was conducted in duplicate and the mean value was used for the determination of Kinematic viscosity. Dynamic viscosity was then calculated by putting the values of Kinematic viscosity and density of test item in the
given formula.

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

1. Calculation of Kinematic Viscosities:
For Test Temperature at 30°C
ν=ct
= 201 × 0.247sec
= 49.6470mm²/sec
For Test Temperature at 50°C
ν=ct
= 195 × 0.247sec
= 48.1650 mm²/sec
2. Calculation of Dynamic Viscosities:
For Test Temperature at 30°C
ν= η/ρ
49.6470 =η 1.0816
η = 49.6470 x 1.0816
= 53.6981 mPa.S
For Test Temperature at 50°C
ν= η/ρ
48.1650 =η/ 1.0816
η = 48.1650 x 1.0816
= 52.0952 mPa.S
