Question

Assume that the left side of your heart creates a pressure of 118 mm Hg by exerting a force directly on the blood over an effective area of 16.0 cm^2. What force does it exert to accomplish?

Answer 1

Answer:

251.5 x 10⁻⁴ N  

Explanation:

Pressure = Force / surface area

Force = pressure x area

pressure = 118 mm of Hg

= .118 x 13.6 x 9.8 N / m²

= 15.72 N / m ²

area = 16 x 10⁻⁴ m²

Force = 15.72 x 16 x 10⁻⁴

= 251.5 x 10⁻⁴ N  .
