A container with volume 1.63 L is initially evacuated. Then it is filled with 0.226 g of N2. Assume that the pressure of the gas is low enough for the gas to obey the ideal-gas law to a high degree of accuracy.If the root-mean-square speed of the gas molecules is 192 m/s , what is the pressure of the gas? Express the answer in pascals.
An Aircraft engine cylinder has a piston displacement of 45 cubic inches and a clearance volume of 10 cubic inches. If the intake pressure is 14.7 PSIA what is the absolute pressure when the piston is at TDC? What is the compression ratio?
Tire gauges for air pressure, as well as most other gauges used in an industrial environment take into account the pressure due to the atmosphere of the Earth. That's why your car gauge reads 0 before you put it on your tire to check your pressure. This is called gauge pressure. The real pressure within a tire or other object containing pressurized stuff would be a combination of what the gauge reads as well at the atmospheric pressure. If a gauge on a tire reads 13.55 psi, what is the real pressure in the tire in pascals? The atmospheric pressure is 1.01x105 Pa.
The small capillaries in the lungs are in close contact with the alveoli. A red blood cell takes up oxygen during the 0.5 s that it squeezes through a capillary at the surface of an alveolus. What is the diffusion time for oxygen across the 1-μm -thick membrane separating air from blood? Assume that the diffusion coefficient for oxygen in tissue is 2×10^−11 m2/s. Give your answer to 1 significant figure.
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?

A 1.50 mL syringe has an inner diameter of 5.50 mm, a needle inner diameter of 0.230 mm, and a plunger pad diameter (where you place your finger) of 1.2 cm. A nurse uses the syringe to inject medicine into a patient whose blood pressure is 140/100. What is the minimum force the nurse needs to apply to the syringe? The nurse empties the syringe in 2.10 s. What is the flow speed of the medicine through the needle?
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 39 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 1.45 in and each refueling took 2.45 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. velocity: m/s
A sphygmomanometer is a device used to measure blood pressure, typically consisting of an inflatable cuff and a manometer used to measure air pressure in the cuff. In a mercury sphygmomanometer, blood pressure is related to the difference in helghts between two columns of mercury. The mercury sphygmomanometer shown in the figure below contains air at the cuff pressure P. Po The difference in mercury heights between the left tube and the right tube is h= 109 mmtg - 0.109 m, a normal systolic reading. What is the gauge systolic blood pressure Poauge in pascals? The density of mercury is p 13.6 x 10 kg/m and the ambient pressure is Po1.01 x 10 Pa. HINT Pa
