Answer to Problem 21P
The systolic pressure from 115
The diastolic pressure from 85
Explanation of Solution
Given data:
A systolic pressure is 115
A diastolic pressure is 85
Formula used:
Formula to determine the gauge pressure is,
Here,
g is the gravitational constant.
h is the height of the fluid column.
Calculation:
Case 1:
Conversion for 115 mm Hg to Pa:
Conversion for 115 mm Hg to psi:
1 mm of Hg is equal to 0.0193368 psi. Therefore,
Conversion for 115 mm Hg to inch of water:
Substitute
Reduce the equation as follows,
