Explanation Given information: Initial velocity of B = v 0 Identical spheres Concept used: General impulse-momentum principal, m v 1 + ∑ I m p 1 → 2 = m v 2 m v 1 − Initial momentum m v 2 − Final momentum ∑ I m p 1 → 2 − Impulse of the force during the time considered. Calculation: Impulse momentum diagram, cos θ = a L General impulse-momentum principal, m v 1 + ∑ I m p 1 → 2 = m v 2 ↗ m v 0 cos θ + 0 = m ( v A ) y + m ( v B ' ) y m ( v A ) y + m ( v B ' ) y = a L m v 0 ............ ( 1 ) ( v A ) y + ( v B ' ) y = a L v 0 Since, ( v A ) y = ( v B ' ) y , ( v A ) y = ( v B ' ) y = a 2 L v 0 The velocity of the sphere A v A = ( v A ) y = a 2 L v 0 General impulse-momentum principal, m v 1 + ∑ I m p 1 → 2 = m v 2 ↘ m v 0 sin θ + 0 = m ( v B ' ) x

The sketch below gives some details of the human heart at rest. What is the total power requirement (work/time) for an artificial heart pump if we use a safety factor of 5 to allow for inefficiencies, the need to operate the heart under stress, etc.? Assume blood has the properties of water. p pressure above atmosphere blood going to the lungs for a fresh charge of oxygen p = 2.9 kPa 25v pulmonary artery d = 25mm fresh oxygenated blood from the lungs p = 1.0 kPa vena cava d=30mm right auricle pulmonary vein, d = 28mm aorta, d=20mm spent blood returning from left auricle the body p = 0.66 kPa right left ventricle ventricle blood to feed the body, p 13 kPa normal blood flow = 90 ml/s

4- A horizontal Venturi meter is used to measure the flow rate of water through the piping system of 20 cm I.D, where the diameter of throat in the meter is d₂ = 10 cm. The pressure at inlet is 17.658 N/cm2 gauge and the vacuum pressure of 35 cm Hg at throat. Find the discharge of water. Take Cd = 0.98.
