Problem 60P

Consider a centrifugal blower that has a radius of em and a blade width of 8.2 cm at the impeller inlet, and a radius of 45 cm and a blade width of 5.6 cm at the outlet. The blower delivers air at a rate of 0.70 m3/s at a rotational speed of 700 rpm. Assuming the air to enter the impeller in radial direction and to exit at an angle of 50° from the radial direction, determine the minimum power consumption of the blower. Take the density of air to be 1.25 kg/m3.

RESPIRATORY PHYSIOLOGY  Example exam question: You’re driving your horse to a race, and there is a hole in the trailer near the exhaust pipe. By the time you get to the horse race, you open the door and what happens (There will be a wreck and the horse will bleed out, this will involve the cardiovascular system) o The horse falls out dead.  The major function of the respiratory system is the exchange of gases. o Two major gases we exchange are carbon dioxide and oxygen. o We are dependent upon the concentration of the gases in the air we breathe (the atmosphere.) If the concentration changes, that disrupts the respiratory system.  Going up really high, there’s not much oxygen. We are dependent on a certain threshold amount of oxygen, and without it you go unconscious.  You need oxygen in the electron transport chain to pull electrons off of the third complex. Without it you stop producing ATP, and your nervous system collapses. BRONCHIAL TREE  Alveoli- Air sacs where gas exchange occurs. In all species. Continuous with the atmosphere. On the other side is a dense net worth of capillary beds. This brings the atmosphere in proximity of the cardiovascular system so gas exchange occurs.  In most mammals, there are 23 branches of the bronchial until you reach the very bottom aspect of the lung.  G
