What does the term "Reynolds number" in fluid dynamics characterize?2 pointsViscosity of the fluidTurbulence intensityRate of heat transfershear stress of fluid

What type of flow is observed when the Reynolds number (Re) is very small (below Re < 5)?*2 pointsLaminar flowTurbulent flowTransitional flowInertial flow

A flow is said to be one-, two-, or three-dimensional _____.Group of answer choicesdepending on whether the flow is laminar, transitional, or turbulentif the flow velocity varies in one, two, or three primary dimensions, respectively.if there are no changes in properties, velocity, temperature, etc., at a point with timedepending on the level of variation of density during flow

What type of fluid behavior is observed when there are deviations from the linear plot between viscosity and shear rate?*2 pointsNewtonian behaviorNon-Newtonian behaviorViscous behaviorInertial behavior

It should be noted that although stress and strain are often used interchangeably, the terms are not used interchangeablyin rheology: stres s is synonymous with force per unit area or a system of forces per unit area, and strai n refers to deformation(i.e., a change in shape or size). A fluid is said to exhibit Newtonian flow if the viscosity is a constant that is independentof the shear rate or applied shear stress. Because viscosity depends on temperature, the temperature of the substancebeing measured should be controlled to within ±0.1

At the critical Reynold's Number there is a transition from:Question 5Select one:a.laminar to partially turbulent flow conditions. This increases the turbulent wake behind the object causing a dramatic increase in form dragb.laminar to partially turbulent flow conditions. This decreases the turbulent wake behind the object causing a dramatic decrease in form dragc.partially turbulent to fully turbulent flow conditions. This increases the turbulent wake behind the object causing a dramatic increase in form dragd.partially turbulent to fully turbulent flow conditions. This decreases the turbulent wake behind the object causing a dramatic decrease in form drage.none of the answers are correct
