Question

Determine the heat transfer rate from the rectangular fin of
length 20 cm, width 40 cm and thickness 2 cm. The tip of
the fin is hot insulated and the fin has a thermal conductivity
of 150 W/MK. The bare temperature is 100°C and the
fluid is at 20°C. The heat transfer coefficient between the
fin and the fluid is 30 W/m K.​

Answer 1

Answer:

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 systemDuring 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.
