Even after the collision there will be no change in the time period of flight as in an elastic collision the ball will bounce with same angle as angle of incident and with same velocity as incident velocity so the trajectory will be just like mirror image of original trajectory about the wall. so time of flight will remain unchanged i.e.,

1. The figure is a drawing of the human trachea airways during normal breathing and during a cough in case of an asthmatic attack. Positive intrathoracic pressure inverts the noncartilaginous portion of the intrathoracic trachea and decreases its cross-sectional area from 1.5 to 0.25 cm. There is also an increase of volumetric flow rate from about 1 to 7 L/sec. Estimate the hydraulic diameter of the trachea in each case. Calculate the Reynolds number for each condition and determine if flow is laminar and turbulent. Pi = 1.2 kg/m^3, μ = 1.81 x 10^-5 kg/ms. Using the string technique, the trachea perimeters were calculated as wetted perimeter for normal = 5.425 cm, wetted perimeter for cough = 7.35 cm. NORMAL COUGH 1.5 cm 0.25 cm 2. The cooling system for a piece of medical equipment has a flow distributor formed of 3 cylindrical tubes with the indicated dimensions. Note that Tubes 2 and 3 are identical. If Tube 2 becomes fully blocked by corrosion, but Tubes 1 and 3 are unaffected, what will the percentage change in pressure drop (ΔP/AP) be between the inlet and the outlet of tube 3 (Point Z)? You may assume that the flow rate Q entering the system is constant and you may neglect any pressure drop in the flow splitter (but not in the tubes themselves). The resistance of a rigid tube in laminar conditions can be calculated from the formula: R = (128μL)/(πD^4). Flow splitter Diameter, D Tube 1 Tube 2 Tube 3 Tube 1 20 cm 1 cm Tube 2 & 3 30 cm 0.5 cm Please calculate emergency all questions 1 and 2.
