Question

Blood pressure is measured in the unit mmHg. The blood pressure is about 120mmHg when it is forced from the heart on its journey around the body and falls to about 80mmHg before the next contraction of the heart. Express these pressures in the unit Pa.

Answer 1

Solution

1 mm Hg = 133.322 pascal

Hence 120 mm Hg = 120*133.322 pascal

15998.64 pascal

Similarly

80 mm Hg = 80*133.322 pascal

10665.76 pascal

So answer is

15998.64 pascal

10665.76 pascal
