In a fluid mechanics class, mechanical, civil, or chemical engineering students will learn about viscosity. The value of viscosity of a fluid represents a measure of how easily the given fluid can flow. The higher the viscosity value is, the more resistance the fluid offers to flow. For example, it would require less energy to transport water in a pipe than it would to transport motor oil or glycerin. The viscosity of many fluids is governed by the Newton's law of viscosity ???? = ???? x du/dy , where ???? is shear stress (N/m2), ???? is viscosity, du is change in flow speed (m/s) over a height dy (m). What are the appropriate units for viscosity?
