• Acceleration

• Mass

• Density

The critical factors in flow instrumentation selection and application are: the type of fluid, Reynolds number, flow irregularities and ___.

• Restriction

• Density

• Viscosity

• Gravity

Flow is the ___ of fluid in a system.

• Movement

• Restriction

• Constriction

• Measurement

__ are liquids whose viscosity won't change as long as it is held at a constant temperature, regardless of the size of the shear force.

• Newtonian Fluids

• Non-Newtonian Fluids

• Laminar Fluids

• Turbulent Fluids

Time-independent non-Newtonian fluids that don't vary with time. The viscosity vary with increases or decreases in shear stress.

• Class I

• Class II

• Class III

• Class IV

It is commonly perceived as thickness or resistance to pouring.

• Restriction

• Density

• Viscosity

• Newtonian

Dynamic viscosity or ___ viscosity is measure of the resistance to a fluid to deformation, or resistance of flow.

• Static

• Absolute

• Guaranteed

• Variable

Kinematic viscosity is the dynamic viscosity of a fluid divided by the ___ of the fluid.

• Pressure

• Density

• Temperature

• Reynolds Number

__ is a quantity that used to predict fluid flow patterns in different situations.

• Pressure

• Viscosity

• Temperature

• Reynolds Number

__ occur at high Reynolds number greater than 4000, where inertial forces are dominant.

• Laminar Flow

• Turbulent Flow

• Transitional Flow

• No Flow
