The bonobos, also called the pygmy chimpanzee, are an endangered species of great apes found in central Africa. Their pulmonary artery, which connects the heart to the lungs, has an inner radius of 3.01 mm and is 8.4 cm long. If the pressure drop between the heart and lungs is 387 Pa, what is the average speed of blood in the pulmonary artery? Blood has a viscosity of 2.7 x 10-3 N · s / m2 and a density of 1060 kg/m3.
Local authorities of Ankara built a basin as cylindrical tank with an upper diameter D1 = 1500m, lower diameter D2 = 750m and height H = 25m, in Ankara as shown in the figure. Nowadays we face out drought periods, the water height in the basin is at the level of 9 m. This value should not fall below 5 m (critical point). Regional officials estimate that the consumption rate in the city is 71620 m / day from the pipe with 2 m in diameter, and the water inlet flow rate from various source (rainfall, current) to the basin will be 150000 m3/ day. The independent variable shows the time in t days, and how long does the water level in the tank (basin) reach the critical value?(ρ = 1000kg / m3)
The small capillaries in the lungs are in close contact with the alveoli. A red blood cell takes up oxygen during the 0.5 s that it squeezes through a capillary at the surface of an alveolus.

Give your answer to 1 significant figure.

The plunger of a syringe has an internal diameter of 1.0 cm and the end of the needle has an internal diameter of 0.35 mm. A practitioner lightly squeezes the plunger, but no serum is emitted by the needle into a vein. So the practitioner gradually increases the squeezing force that she exerts on the plunger such that serum begins to be emitted from the needle into the vein. Assuming no surface tension or friction, what is the minimum squeezing force that the practitioner applies to the plunger in order that serum begins to be emitted from the needle into the vein? Take the pressure of blood in the vein to be 20 mmHg above that of atmospheric pressure. 0.70 N 3.3 N 0.21 N 0.24 N 1.4 N 17N
