Air at 110 kPa and 50°C flows upward through a 6 cm diameter inclined duct at a rate of 45 L's. The duct diameter is then reduced to 4 cm through a reducer. The densities of air and water are known to be 1.19 and 1000 kg m', respectively. The pressure change across the reducer is measured by a water manometer. The elevation difference between the two points on the pipe where the two arms of the manometer are attached is 20 cm. Determine the differential height between the fluid levels of the two amms of the manometer

Answer:
During gas exchange oxygen moves from the lungs to the bloodstream. At the same time carbon dioxide passes from the blood to the lungs. This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.The circulatory system is made up ofblood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. Thecirculatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.A body system is a collection of parts able to work together to serve a common purpose – growth, reproduction and survival. ... The human body is made up of a number of inter-related systems that work together to maintain a stable internal environment. Cardiovascularsystem. The heart and blood vessels make up this system
