- Concrete is pumped from a cement mixer to the place it is being laid, instead of being carried in wheelbarrows. The flow rate is 220 L/min through a 48-m-long, 7.5-cm-diameter hose, and the pressure at the pump is 7.6 × 106 N/m2 .Randomized VariablesQ = 220 L/minl = 48 md = 7.5 cmP = 7.6 × 106 N/m2 Part (a) Calculate the resistance of the hose in N⋅s/m5. Part (b) What is the viscosity of the concrete, assuming the flow is laminar in (N/m2)⋅ s? Part (c) How much power is being supplied, assuming the point of use is at the same level as the pump in W? You may neglect the power supplied to increase the concrete’s velocity.A person is in a closed room (a racquetball court) with V = 435 m3 hitting a ball (m = 37.6 g) around at random without any pauses. The average kinetic energy of the ball is 3.8 J. What is the average value of v2xvx2 in m2/s2? Consider if it matters which direction you take to be x. Calculate the average pressure on the walls in pascals.The heat pumps blood at an average flow rate of 80.0cm^3/s into the aorta, which has a diameter of 1.5cm. Determine the average speed of the blood in the aorta. If the diameter of the aorta is reduced to a diameter of 1.2am, but the volumetric flow is the same, what will the new speed of the blood be?
- Three liquids that will not mix are poured into a cylindrical container. The volumes and densities of the liquids are 0.670 L, 2.77 g/cm³; 0.356 L, 1.20 g/cm³; and 0.524 L, 0.653 g/cm³. What is the force on the bottom of the container due to these liquids? One liter = 1 L = 1000 cm³. (Ignore the contribution due to the atmosphere.) Number i UnitsThe flow rate of blood through a 2.25 ✕ 10−6 m radius capillary is 3.80 ✕ 10−9 cm3/s. (a) What is the speed of the blood flow (in cm/s)? (This small velocity allows time for diffusion of materials to and from the blood.) (b) Assuming all the blood in the body passes through capillaries, how many of them must there be to carry a total flow of 80.0 cm3/s? (The large number obtained is an overestimate, but it is still reasonable.)The average body density of a human is 1030 kg/m3, yet we typically float in seawater when we fill our lungs with air and sink when we exhale. Therefore, our effective density is similar to that of seawater, 1010 kg/m3. If the typical total volume (body density + lung capacity) of a human is 0.25 m3, what volume is due to body mass and what volume is due to lung capacity (you can assume the density of air is rair = 1.2 kg/m3)
- A Venturi meter is a device for measuring the speed of a fluid within a pipe. The drawing shows a gas flowing at speed v2 through a horizontal section of pipe whose cross-sectional area is A2 = 0.0937 m2. The gas has a density of ρ = 1.30 kg/m3. The Venturi meter has a cross-sectional area of A1 = 0.0234 m2 and has been substituted for a section of the larger pipe. The pressure difference between the two sections is P2 - P1 = 149 Pa. Find (a) the speed v2 of the gas in the larger original pipe and (b) the volume flow rate Q of the gas. I posted it just now and recieved the wrong answers so i'm asking again. The answers are not A) 1.87 and B) 0.157.Suppose you spray your sister with water from a garden hose. The water is supplied to the hose at a rate of 0.573 × 10–3 m³/s and the diameter of the nozzle you hold is 5.09 × 10-3 m. At what speed v does the water exit the nozzle?Suppose you measure a standing person’s blood pressure by placing the cuff on his leg 0.495 m below the heart. For this problem, assume that there is no loss of pressure due to resistance in the circulatory system (a reasonable assumption, since major arteries are large). The density of blood is 1.05 × 103 kg/m3. Calculate the systolic pressure you would observe, in units of mm Hg, if the pressure at the heart was 120 over 80 mm Hg. Note that the to (and greater) number is systolic pressure. Ps? Calculate the diastolic pressure you would observe, in unites of mm Hg, if the pressure at heart was 120 overc80cmm Hg. Note that the bottom (smaller) number is the diastolic pressure.Pd?
- A simple thermometer is formed by taking a large spherical container of volume 1.13m³ and filling it with an ideal gas. Then, a U-shaped tube is attached that is very narrow so that very little fluid/gas can fit inside the tube. The tube has a small quantity of a fluid of density 1200kg/m³ placed in it. In equilibrium at room temperature - 21.9°C - the height of the fluid on both sides of the U-shaped tube are level. This is illustrated in the image below. What is the temperature of the gas in the spherical container when the left side of the fluid is 13.25cm higher than the right side of the fluid in the U-shaped tube? Atmospheric pressure is 101000Pa. °CAs blood is pumped from the heart, it moves through the ascending aorta and then down the descending thoracic aorta. The ascending aorta has an average cross-sectional area of approximately 7.07cm2, while the descending aorta has an average cross-sectional area of 4.52cm2. The heart pumps out blood at an average flow rate of 0.0800 L/s . Determine the average speed of blood through the ascending aorta:___cm/s Determine the average speed of blood through the descending aorta: ___cm/sssm A patient recovering from surgery is being given fluid intravenously.
