Phys 115 1st Edition Lecture 4Outline of Last Lecture I. Ideal FluidsII. Continuity equationIII. Bernoulli’s equationOutline of Current Lecture IV. ViscosityV. Poiseuille’s EquationCurrent Lecture- Viscosity (η)o Resistance to flowo Increase in viscosity, slower the flowo Honey is more viscous than watero Units of Pa*so Units of centipoise (10-3 Pa*s)o Requires a change in pressure to overcome drago Doesn’t have a single speed Speed increases away from wall Wall creates friction Therefore, we find the average speedo Average speed (Q) L decreases the flow rate because a longer tube has more friction- CR1o B, average speed is direction proportional to change in pressure- CR2o C, average speed is proportional to area- CR3o 800 Pa- CR4o Q is inversely proportional to viscosityThese 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.- CR5o Purple
