The flow of blood in veins and arteries is a transient proce

The flow of blood in veins and arteries is a transient process in which the elastic conduits expand and contract.At some instant in time, the inner radius has a radial velocity of 0.012 cm/s. The length of the artery is 13 cm and the volumetric flow rate at the entrance of the artery is 0.3 cm3/s. If the inner radius of the artery is 0.15 cm, at the particular instant of time, what is the volumetric flow rate at the exit of the artery?

Solution

volumetric flow rate will be same at the intrance and exit.

so flow rate = 0.3 cm^3 / s
