Using the appropriate equations, predict the effects in each scenario. a. Vessels X and Y have the same diameter. X is 5 cm long and Y is 10 cm long. Which has the faster velocity of flow for the same fluid? b. A blood vessel has a radius of 4 cm. Vasoconstriction reduces the radius to 1 cm. In order to maintain the same flow, by what factor must pressure increase? c. The blood vessel in B above dilates from 1 cm to 4 cm. Does the flow rate increase or decrease?
