Q1. a) In an adult, the aorta's radius is normally 1.5 cm and blood moves through it at the average velocity of 30 cm/s. If a typical capillary vein has a constant radius of 5 x10m and blood passes through them with a velocity of 0.1 cm/s, approximately how many capillaries are needed in a body? b) Benzene at 1 atm and 80°C enters the pipe system given in the below figure, with a Reynolds number of 130000 and leaves the system at 60°C. Assuming that diameters of the pipes at the exit are equal to each other, calculate the Reynolds number on one of the exit pipes (density of liquid benzene at 80° C= 813 kg/m' and at 60°C = 835 kg/m³). 3 in st 80 5 in st 80 3 in st 80

SHOW THE TABLE USED! A fixed amount of carbon dioxide goes through a polytropic process where n=1.4. The initial temperature of the CO2 is 250 K. The final temperature of the CO, is 400 K. If the mass of the CO2 is 12 kg and behaves as an ideal gas, determine the work, the change in internal energy, and the heat transfer during the process (in kJ). Note that PV=mRT. In this problem, can the carbon dioxide be considered an ideal gas at the initial conditions if the initial pressure is 150 kPa? Justify your answer quantitatively.
