2. Problem 1.15. from the book. [Statement: The pressure difference, Δp, across a partial blockage in an artery (called a stenosis) is approximated by the equation: ∆P = Kv μV D + Ku ( A0 A1 − 1) 2 rhoV 2 where V is the blood velocity, μ the blood viscosity (FTL-2 ), rho the blood density (ML-3 ), D the artery diameter, Ao the area of the unobstructed artery, and A1 the area of the stenosis. Determine the dimensions of the constants KV and Ku. Would this equation be valid in any system of units?]

You have two photos of a person walking. one shows the person at the corner of third and main streets, the other shows the person at the corner of tenth and main streets. there are lampposts at every corner in this town, and the first picture shows it to be 10: 32: 00 exactly. the second picture shows it to be 10: 49: 30. you know three facts: (1) all of the clocks are synchronized; (2) there are exactly 12 equal-sized blocks per kilometer in this town; and (3) the streets that cross main in this area are numbered consecutively, with no interruptions. what is the person’s average speed in kilometers per hour?
