a) In an adult, the aorta’s radius is normally 1.5 cm and blood moves through it at the average velocity of 30 cm/s. If a typical capillary vein has a constant radius of 5 x10-6m and blood passes through them with a velocity of 0.1 cm/s, approximately how many capillaries are needed in a body? b) Benzene at 1 atm and 80⁰C enters the pipe system given in the below figure, with a Reynolds number of 130000 and leaves the system at 60⁰C. Assuming that diameters of the pipes at the exit are equal to each other, calculate the Reynolds number on one of the exit pipes (density of liquid benzene at 80⁰ C= 813 kg/m3 and at 60⁰C = 835 kg/m3).

Question
a) In an adult, the aorta’s radius is normally 1.5 cm and blood moves through it at the
average velocity of 30 cm/s. If a typical capillary vein has a constant radius of 5 x10-6m and
blood passes through them with a velocity of 0.1 cm/s, approximately how many capillaries are
needed in a body?
b) Benzene at 1 atm and 80⁰C enters the pipe system given in the below figure, with a Reynolds
number of 130000 and leaves the system at 60⁰C. Assuming that diameters of the pipes at the
exit are equal to each other, calculate the Reynolds number on one of the exit pipes (density of
liquid benzene at 80⁰ C= 813 kg/m3
and at 60⁰C = 835 kg/m3).
