(a) Determine the speed at which blood is flowing through an artery with a radius of 5.60 10-3 m, if the artery is supplying blood to the brain at a volume flow rate of 3.90 10-6 m3/s.  m/s (b) If the flow rate is to remain the same through a constriction that reduces the radius of the artery by a factor of 3, determine the speed at which blood must flow through the constricted region. m/s

If liquid enters a horizontal conduit with circular cross-sectional radius of 2 m at 8 m/a and exists the conduit a short distance later after the cross-sectional radius has increased to 2.5 m, what is the density of the fluid if the pressure is 11,000 Pa greater at the exit?

A glucose solution being administered with an IV has a flow rate of 3.95 cm3/min Q = 3.95 cm3/min a. What will the new flow rate be if the glucose is replaced by whole blood having the same density but a viscosity 2.50 times that of the glucose in cm3/min? All other factors remain constant.

A hospital patient receives a 600-cc blood transfusion through a needle with a length of 5cm and an inner diameter of 1mm. If the blood bag is suspended 0.75m above the needle, how long will the transfusion take? (You can neglect the viscosity of the blood flowing in the plastic tube between the bag and the needle. Note also that 1 cc = 10-6 m3and that blood has a mass density of ρ = 1060kg m-3 and a molecular viscosity of μ = 3.5 x 10-3 kg m-1 s-1).
