Q1. 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 x10m and blood passes through them with a velocity of 0.1 cm/s, approximately how many capillaries are needed in a body?

Q1. 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 x10m 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 80°C enters the pipe system given in the below figure, with a Reynolds number of 130000 and leaves the system at 60°C. 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 80° C= 813 kg/m' and at 60°C = 835 kg/m³). 3 in st 80 5 in st 80 3 in st 80
