If blood is flowing through it with a volume flow rate of 9 X10-7 m3/s, w hat is the difference in the pressures at the two ends of the blood vessel?

Explanation / Answer

Here ,

length , L = 16 cm = 0.16 m

radius ,r = 1.7 mm = 0.0017 m

volume flow rate , V = 9 *10^-7 m^3/s

viscocity of water , n = 8.9 *10^-4 Pa.s

pressure drop = 8 * n * V * L/(pi * r^2)

pressure drop = 8 * 8.9 *10^-4* 9 *10^-7 * 0.16/(pi * (0.0017)^4)

pressure drop = 39.07 Pa
