(chatquestion)...24. The aorta is the principal blood vessel through which blood leaves the heart in order to circulate around the body. (a) Calculate the average speed of the blood in the aorta if the flow rate is 5.0L/min. The aorta has a radius of 10mm. (b)Blood also flows through smaller blood vessels known as capillaries. When the rate of blood flow in the aorta is 5.0 L/min, the speed of blood in the capillaries is about 0.33 mm/s. Given that the average diameter of a capillary is 8.0µm, calculate the number of capillaries in the blood circulatory system.

(chatquestion)...90 Chapter 3 Methods of Analysis Example 3.3 For the circuit shown in Fig. 3.9, find the node voltages. 10 Q Solution: The supemode contains the 2-V source, nodes 1 and 2, and the 10-N resistor. Applying KCL to the supernode as shown in Fig. 3.10(a) gives 2 = i, + iz + 7 2A 4Ως (+ 7A Expressing i, and iz in terms of the node voltages U2 8 = 2v, + v2 + 28 Figure 3.9 For Example 3.3. or v2 = -20 - 2v, (3.3.1) To get the relationship between vị and v2, we apply KVL to the circuit in Fig. 3.10(b). Going around the loop, we obtain -u, - 2 + v2 = 0 U2 = v, + 2 (3.3.2) From Eqs. (3.3.1) and (3.3.2), we write Uz = v, + 2 = - 20 – 2v, or 3v, = -22 v, = -7.333 V and v2 = v, + 2 = -5.333 V.

It is a threat to the quality of life, country's economy and future development. The current rate of deforestation is estimated to be more than 10 million ha/year. If this rate continues, it is feared that the remaining tropical forest may dissappear within a century. > Causes of deforestation : The main causes are as follows- O Explosion of human population : Due to over population of human beings, requirement of timber, fuel, paper, wood etc. has increased.
