Blood pressure is usually measured by wrapping a closed air-filled jacket equipped with a pressure gage around the upper arm of a person at the level of the heart. Using a mercury manometer and a stethoscope, the systolic pressure (the maximum pressure when the heart is pumping) and the diastolic pressure (the minimum pressure when the heart is resting) are measured in mmHg. The systolic and diastolic pressures of a healthy person are about 120 mmHg and 80 mmHg, respectively, and are indicated as 120/80. Express both of these gage pressures in kPa, psi, and meter water column. Take the densities of water and mercury as 1000 kg/m3 and 13,600 kg/m3, respectively. The high and low pressures, in kPa, are kPa and kPa, respectively. The high and low pressures, in psi, are psi and psi, respectively. The high and low pressures, in meter water column, are m and m, respectively.
