The pressure difference, across a partial blockage in an artery (called a stenosis) is approximated by the equation

where V is the blood velocity, μ the blood viscosity (FL^-2T), p the blood density (ML^-3)the artery diameter, the area of the unobstructed artery, and A₁ the area of the stenosis. Determine the dimensions of the constants K_v and K_u. Would this equation be valid in any system of units?
