Question

Calculate the maximum force in newtons exerted by the blood on an aneurysm, given the maximum blood pressure for this person is 150 mm Hg, and the effective area of the aneurysm is 20.0 cm^2.

a) 300 N
b) 30 N
c) 3,000 N
d) 0.3 N

Answer 1

The maximum force exerted by the blood on the aneurysm is 300 N.

Step-by-step explanation:

To calculate the maximum force exerted by the blood on an aneurysm, we can use the formula:
Force = Pressure x Area

Given that the maximum blood pressure is 150 mm Hg and the effective area of the aneurysm is 20.0 cm², we can substitute these values into the equation:
Force = (150 mm Hg) x (20.0 cm²)

Converting the units to SI units, where 1 mm Hg = 133.3 Pa and 1 cm² = 0.0001 m², the force can be calculated as:
Force = (150 mm Hg) x (20.0 cm²) x (133.3 Pa/mm Hg) x (0.0001 m²/cm²)

Simplifying the calculation, we find that the maximum force exerted by the blood on the aneurysm is approximately 300 N.
