ch time your heart beats, your blood pressure first increases and then decreases as the heart rests between beats. The maximum and minimum blood pressures are called the systolic and diastolic pressures, respectively. Your blood pressure reading is written as systolic/diastolic. A reading of 120/80 is considered normal. A certain person's blood pressure is modeled by the function p(t) = 125 + 25 sin(150?t) where p(t) is the pressure in mmHg (millimeters of mercury), at time t measured in minutes.

A hyperbaric chamber is a sealed chamber in which the air pressure is greater than atmospheric pressure. These chambers are usually fitted with glass viewing ports so the medical staff can monitor the patient inside. If the radius of one such viewing port is 10 cm, and the pressure inside the chamber is 2 times atmospheric pressure, then what is the approximate outward force on the viewing port due to the air inside?
In 1923, the United States Army (there was no United States Air Force at that time) set a record for in-flight refueling of airplanes. Using two refueling planes, an Airco DH-4B biplane was able to remain in flight for 38 h. During the flight, the refueling planes were able to air-transfer a total of 687 gallons of fuel to the plane in 9 refueling transfers. Assume that the refueling nozzle had a diameter of 1.25 in and each refueling took 2.47 min to perform. Calculate the velocity of the fuel through the nozzle. Assume that the fuel filled the entire cross-sectional area of the nozzle.

The tympanic membrane, or eardrum, is a structure that separates the external and middle parts of the ear (see the figure). It is sensitive to and vibrates in response to changes in air pressure and transmits these vibrations to other structures in the inner ear that lead to the sensation of hearing. Under normal conditions, the pressure on the inside and outside of the tympanic membrane are kept approximately equal. The auditory tube, also called the Eustachian tube, is responsible for this equilibration. However, rapid changes in external pressure can cause large pressure differentials on the tympanic membrane, causing it to rupture. A differential force across the eardrum membrane as little as 5.0 N can cause a rupture. (a) If the cross-sectional area of the membrane is 1.0 cm², what is the maximum tolerable pressure difference between the external and inner ear? (b) Based on your answer in part (a), to what maximum depth could a person dive in fresh water before rupturing an…

A sphygornanorneter is a device used to measure blood pressure. It is consisted of an inflatable cuff and a manometer with one end connected to the cuff and the other to the open atmosphere. Blood pressure is measure by h, the difference in the heights between the two colurnns of mercury. If a normal heart pumps out blood with guage pressure 15931 Pa, what reading do we expect to read?
