2) The pressure difference, AP, across a partial blockage in an artery is approximated by the equation 2 リ。 AP = Kv + Ku 1 \41 where V is the blood velocity, u the blood viscosity (FL-2T), p the blood density (ML-3), D the artery diameter, Ao the area of the unobstructed artery, and A1 the area of the stenosis. Determine the dimensions of the constant Ky and Ku. Would this equation be valid in any system of units?
