Question 102

For a certain patient,the build-up of fatty tissue on the wall of an artery has decreased the arterial radius by 10%.By how much would the pressure provided by the heart have to be increased to maintain a constant volume of blood flow? Model the blood as an ideal incompressible fluid.
