The pressure difference, across a partial blockage in an artery $($called a stenosis$)$ is

approximated by the equation

Where: v $=$ blood velocity; u $=$ blood viscosity; p $=$ blood density; D $=$ artery diameter;

AO

area of the unobstructed artery, and A $=$ area of the stenosis. Determine the

dimensions of the constants K$,$ and K
