Question

Blood pressure is measured when the blood is pumping (systolic) and when the heart is resting (diastolic). When pressure readings are given, the systolic is given first, and healthy blood pressure is around 120 over 80 mm Hg. Recall the density of mercury is 13.6 times 10^3 kg/m^3. Suppose you have a blood pressure reading of 122 over 78 mm Hg. What is your systolic pressure, in newtons per meter squared? Suppose you have a blood pressure reading of 122 over 78 mm Hg. What is your diastolic pressure, in newtons per meter squared?

Explanation / Answer

Here ,

density , p = 13.6 *10^3 Kg/m^3

a) for the pressure

P = p * g * h

P(122 Hg) = 13.6 *10^3 * 9.8 * 122 *10^-3

P(122 Hg) = 16260 N/m^2

the systolic pressure is 16260 N/m^2

b) for the diastolic pressure

diastolic pressure = p * g * h

diastolic pressure = 13.6 *10^3 * 9.8 * 0.078

diastolic pressure = 10396 N/m^2

the diastolic pressure is 10396 N/m^2
