The volume flow rate in an artery supplying the brain is 4.00 10-6 m3/s. (a) if the radius of the artery is 4.50 10-3 m, determine the average blood speed. m/s (b) find the average blood speed at a constriction in the artery if the constriction reduces the radius by a factor of 4. assume that the volume flow rate is the same as that in part (a).

The magnitude of the amount of energy released by burning a fuel source, measured in energy per unit mass, is called its fuel value. note that the fuel value is the negative of the isobaric specific heat of combustion for the fuel. if all the energy obtained from burning 1.23 pounds of butane with a fuel value of 10.85 kcal/g is used to heat 128.0 kg of water at an initial temperature of 18.3 °c, what is the final temperature? note that 1 lb = 453.6 g.
