Explain the relationship between the area of a tube and fluid’s velocity. 2. If a pipe with flowing water has a cross-sectional area nine times greater at point 2 than at point 1, what would be the relation of flow speed at the two points? 3. Blood travels through an artery at velocity v. If a vasoconstriction chemical is consumed and the artery constricts to half the original diameter, what is the new velocity of the blood? 4. Explain Bernoulli’s principle. Give an example how this principle is being applied or observed in our daily lives

3. DETAILS A medical patient's femoral artery has an internal cross-sectional area of 0.38 cm² and a blood volume flow rate of 2.30. min Determine the blood flow speed through the artery (round to the nearest thousandth). m S MY NOTES m S ASK YOUR TEACHER Plaque buildup in one region of the artery creates a smaller cross-sectional area of 0.13 cm². Determine the blood flow speed through this partially blocked region of the artery (round to the nearest thousandth). If the blood pressure through the unobstructed artery is 14250 Pa, determine the blood pressure through the partially blocked region. Assume blood has the same density of water, blood-1000 kg Pa m3

Which of the following statements regarding the presented form of Bernoulli's equation are true? 1 P₁+ + = pw² + pgz₁ = P₂ + = pw² + pgzz Select one or more: U a. The flow is steady and frictionless. Ob. Flow friction is taken into account in the equation. O c. The equation describes energy conservation in a flow. Od. The middle streamline of the flow has to remain on a same level, which means the equation can only be used when zand z2 are equal. Oe. The equation has terms for kinetic energy, potential energy, and pressure. O f. The flow is transient and frictionless.

A. Keeping the radius and length the same, how would doubling the height of the drip bagchange the flow rate of fluid? (Be quantitative)B. Keeping the height of the drip bag and length of the cannula the same, how would doublingthe radius of the cannula affect the flow rate of fluid?C. Keeping the radius of the cannula and height of drip bag the same, how would doubling thelength of the cannula affect the flow rate of the fluid?D. Hypodermic needles (and the cannulae attached to them) are described by numbers known as"gauge". Patients commonly receive "18 Gauge", "20 Gauge", and "22 Gauge" cannulae. Largergauges correspond to smaller radii. The radius of the tube, for a given gauge, is summarized onthis webpage. Is the outside diameter (OD) or inside diameter (ID) more relevant to calculatingfluid flow? Why?
