In 1896, S. Riva-Rocci developed the prototype of the current sphygmomanometer, a device used to measure blood pressure. When it was worn as a cuff around the upper arm and inflated, the air pressure within the cuff was connected to a mercury manometer. The density of mercury is 13,550 kg/m3. Assume all pressures are gage pressures Part A The reading for the high (or systolic) pressure is 120 mm. Determine this pressure in pascals and psi. Express your answers using three significant figures separated by a comma. pPa, ppsi = nothing Pa, psi Request Answer Part B The reading for the low (or diastolic) pressure is 80 mm. Determine this pressure in pascals and psi. Express your answers using three significant figures separated by a comma. pPa, ppsi = nothing Pa, psi
