The international systems of units (SI) measures the unit of viscosity in newton seconds per meter squared (Ns/m2) which is synonymous to a Pascal second Defines viscosity as the measure of its resistance to deformation at a given rate which corresponds to the informal concept of thickness for liquids. The property that accounts for these differences in properties of flow is known as viscosity. Not all liquids are the same some a thin and flow fast while some are thick or gooey and flow slowly. KeywordsCorrosion resistance, pumpability, shelf life, sprayability, viscometer This proves that the viscometer produced is reliable and conforms to standards and can be used in laboratories, construction industries, food processing industries and for educational purposes. These values compare closely with different literatures and a significant average percentage error of 5.9%. The fabricated viscometer was used to test kerosene, ethanol and plasma and yielded the following results 0.00134, 0.0011 and 0.0034 respectively. The following considerations was used in designing the viscometer corrosion resistance for selection of materials, ease of fabrication and usage.

This paper presents the design, fabrication and testing of a viscometer that measures viscosity of fluids by virtue of its flow rate through a discharge orifice. It is therefore important that related measurements should be carried out with equipment that is accurate and less expensive. Conclusions about their processing characteristics, pumpability, sprayability shelf life, as well as flowability and application characteristics can be retrieved from successful measurements. Plasters, sealers bond breakers, liquid floor hardeners, coatings and more are liquids used in the construction industry. The construction industry makes use of different liquids for different applications. Knowledge of viscosity and flow parameters are essential in liquids for their production, quality control and development.
