Fluid TypesII. Fluid PropertiesIII. How to Measure Surface TensionIV. Ring TensiometerCurrent LectureChapter 1Fluid Types- Newtoniano Constant velocity with respect to sheer rate- Non-newtoniano Viscosity is a function of sheer- Bingham fluido Flow only when yield stress is exceeded- Sheer thinning fluido Contains components that can deform and rearrange to accommodate the flow (entropy is overcome by external force)- Sheer thickening fluido Contains components that cannot deform or rearrange to accommodate the flow- Power law modelo N: power law index N=1 – Newtonian N<1 – sheer thinningThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute. N>1 – sheer thickeningFluid Properties- Kinematic viscosityov =μρ- Surface tensiono Work needed to increase interfacial area Surface tension area is important Gravity volume is important- Laplace equationoP1−P2=σ (1r1+1r2)- Relevant surface tensionoPβ−Pα=2 σro Work approaches zero for an irreversible process- How to measure surface tensionoσ =ρgha2 cosθoa=rcosθ- Ring tensiometeroσ =F2 π
