Question

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.

Expert Solution

Step 1

Given data:

the radius of the pulmonary artery, r = 3.01 mm = 0.00301 m

length of the pulmonary artery, L = 8.4 cm = 0.084 m

The pressure drop between the heart and lungs, ΔP = 387 Pa

the density of blood, ρ= 1060 kg/m³

The viscosity of blood, μ = 2.7 x 10^-3 N · s / m²
