The SYSTOLIC pressure in a major artery is measured at 115 mmHg. What is the net force on a 1 cm2 section of the artery wall if the absolute pressure in the tissue outside the arterial wall is 108.6 kPa?

Dr.B

a mmHg equals 133.3 Pa (google conversion)
find the pressure difference (in kPa)
a Pascal is a Newton per m^2 ... 10^4 cm^2posted by Scott
