Valvular Pressure Drop: Blood flow velocities across a calcified aortic valve are u₁ =0.25 m/s in the left ventricle and u₂ = 1 m/s in the aorta. Assuming a blood densityuzof 1060 kg/m³, find the following:a. What is the estimated pressure drop across the valve in mmHg using Bernoulli'sequation? (Neglect potential energy differences.)b. What is the estimated pressure drop across the valve using the clinicalapproximation of Ap≈ 4u3? (In the clinical approximation, Ap is in mmHg and uis in m/s.)c. Compare values and compute the % error in the clinical approximation.

Fluids must move across control volume boundaries to achieve flow work per unit mass; P is pressure.…
