Poiseuille’s law for fluid velocities Poiseuille’s law describes the velocities of fluids flowing in a tube---for example, the flow of blood in a vein. (See Figure 5.74) This law applies when the velocities are not too large----more specifically, when the flow has no turbulence. In this case, the flow is laminar, which means that the paths of the flow are parallel to the tube walls. The law states that

- 5-6 Yes or No? If No, give a reason aIs the average rate of change of a function between x=a and x=b the slope of the secant line through (a,f(a)) and (b,f(b))?arrow_forwardLIFE SCIENCE APPLICATIONS Length of a Pendulum Grandfather clocks use pendulums to keep accurate time. The relationship between the length of a pendulum L and the time T for one complete oscillation can be determined from the data in the table. Source: Gary Rockswold.

Find the least squares line equation and graph it simultaneously, if possible, with the data points. Does it seem to fit the data? c. Find the correlation coefficient and interpret it. Does it confirm your answer to part b?arrow_forwardVelocity A car is moving along a straight test track. The position in feet of the car, s(t), at various times t is measured, with the following results. Find and interpret the average velocities for the following changes in t. a. 0to2seconds b. 2to4seconds c. 4to6seconds d. 6to8seconds e. Estimate the instatneous velocity at 4 seconds. i. by finding the average velocity between 2 and 6 seconds, and ii. by averageing the answers for the average velocity in the two seconds before and the two seconds after that is, the answers to parts b and c. f. Estimate the instantaneous velocity at 6 seconds using the two methods in part e. g. Notice in parts e and f that your two answers are the same. Discuss whether this will always be the case, and why or why not.arrow_forward
