Question 4 (1 point) The pulmonary artery, which pumps blood from the heart to the lungs, has an inner radius of (1.5x1040) mm and is (5.80x10^0) cm long. If the pressure drop between the heart and lungs is (4.16x10^2) Pa, what is the volume flow rate of blood in the pulmonary artery? Give your answer in cm /s. The viscosity of blood at 37 C is 2.1 x 10 3 Pa s. Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: x10 Answer Question 5 (1 point) A pipe carries water horizontally at a pressure of (1.700x10 0) atm, with the water flowing at a speed of 2.0 m/s. The water is then to be diverted downwards and continue through a horizontal pipe, but now underneath the ground as shown in the picture below. If the width of the pipe remains constant, and the pipe can withstand a pressure of (4.3x10^0) atm, how far down (relative to its starting position) could the lower segment be placed? Give your answer as a positive value in m (don't include a sign) to 2 sf. Note that the density of water is 1000 kg/m , and that 1 atm 101.3 kPa. Hint: What does the continuity equation tell you about the speed of the water in the lower portion
