A thin stream of water ows smoothly from a faucet and falls straight down. At one point, the water is owing at a speed of v] = 1.23 m/s. At a lower point, the diameter of the stream has decreased by a factor of 0.805. What is the vertical distance h between these two points? A small artery has a length of 1.10 X 10'3 m and a radius of 2.50 X 10'5 m. If the pressure drop across the artery is 145 kPa, What is the ow rate through the artery? Assume that the temperature is 37 \"C and the Viscosity of whole blood is 2.084 x 10-3 Pa-s. Question Credit: OpenStax College Physics
