If the average volume flow of blood through the aorta is 8.50 × 10−5 m3/s and the cross-sectional area of the aorta is 3.00 × 10−4 m2, what is the average speed of blood in the aorta?

At a given instant, the blood pressure in the heart is 1.4 x 104 Pa. If an artery in the brain is 0.37 m above the heart, what is the pressure in the artery? Ignore any pressure changes due to blood flow.

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?

Flow rate is expressed as gas velocity in cm/s. The gas is flowing through an open tubular column with an inner diameter of 0.25 mm. What volume flow rate (mL/min) corresponds to a gas velocity of 50 cm/s? (The volume of a cylinder is pr2 3 length, where r is the radius.)

At a given instant, the blood pressure in the heart is 1.7 x 104 Pa. If an artery in the brain is 0.46 m above the heart, what is the pressure in the artery? Ignore any pressure changes due to blood flow.

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

Grains of fine California beach sand are approximately spheres with an average radius of 50 μm and are made of silicon dioxide, which has a density of 2.5 × 103 kg/m3. What mass of sand grains would have a total surface area (the total area of all the individual spheres) equal to the surface area of a cube 1.2 m on an edge?

A rectangular block of copper alloy has a mass of 1896 g. The dimensions of the block are 8.4 cm by 5.5 cm by 4.6 cm. From this data, what is the density of copper? 9386 kg/m³ O 0.112 kg/m³ 402938 kg/m3 2650 kg/m3 8922 kg/m³ 5498 kg/m³

The density of platinum is 21500 kg/m3 and that of aluminum is 2702 kg/m3. Find the ratio of the volume of 1.20 kg of platinum to the volume of 1.01 kg of aluminum.

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 35 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 1.65 in and each refueling took 2.43 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: 12.94 m/s Incorrect
