viscometer used in syrup and contact lens cleaning solution manufacturing companies, because the syrup should be sum of viscous.
Limit variables. Use accurate measuring equipment. Use multiple trials to obtain data that can be averaged. Observe intently.

REDWOOD'S Viscometer is used to find out the viscosity of an standard rape oil and any of the fluids . The viscometers are classified into 4 types they are 1. Saybolt Viscometer 2. Engler Viscometr 3. Barbey Viscometer & 4. Redwoods Viscometer
νCentistokes = 0.226 νSSU - 195 /νSSUwhereνSSU < 100νCentistokes = 0.220 νSSU - 135 /νSSUwhereνSSU > 100
