Dandelion seeds have a plume made of thin filaments that create a very large drag coefficient due to subtle aerodynamics as the air moves through and past the plume. The slower terminal speed and longer time in the air provide greater dispersal than would be possible for simple spherical seeds.

Prairie dogs are burrowing rodents. They do not suffocate in their burrows,because the effect of air speed on pressure creates sufficient aircirculation. The animals maintain a difference in the shapes of twoentrances to the burrow, and because of this difference, the air blows pastthe openings at different speeds, as the drawing indicates. Assuming thatthe openings are at the same vertical level, find the difference in airpressure between the openings and indicate which way the air circulates.
Find the settling velocity of a 20 microm diameter particle with density 1500 kg/m^3. If this particle had been hurled to a height of 8,000 m during a volcanic eruption, estimate the time required to reach the ground (sea level). You many assume that the viscosity of air does not change enough to worry about. If winds average 10 m/s, how far away would it blow on its way down?
61. ssm Prairie dogs are burrowing rodents. They do not suffocate in their burrows, because the effect of air speed on pressure creates sufficient air circulation. The animals maintain a difference in the shapes of two entrances to the burrow, and because of this difference, the air (p = 1.29 kg/m³) blows past the openings at different speeds, as the drawing indicates. Assuming that the openings are at the same vertical level, find the difference in air pressure between the openings and indicate which way the air circulates. "A = 8.5 m/s vg = 1.1 m/s
If you blow a thin stream of air with a speed of 7.2 m/s out of your mouth, what is the overpressure in your mouth? Assume that the speed of the air in your mouth is (nearly) zero.
The plunger of a syringe has an internal diameter of 1.0 cm and the end of the needle has an internal diameter of 0.30 mm. A practitioner squeezes across the plunger very lightly, but no serum is emitted by the needle into a vein. So the practitioner gradually increases the force that she exerts across the plunger and eventually serum begins to be emitted from the needle into the vein. Assuming no friction, what is the minimum net force that the practitioner applies across the plunger in order that serum begins to be emitted from the needle into the vein? Take the pressure of blood in the vein to be 20 mmHg above that of atmospheric pressure. 3.3 N 1.2N 0.21N 0.70 N 1.4 N O 23 N
pipe 6-77 Water is flowing into and discharging from U-section as shown in Fig. P6-77. At flange (1), the total absolute pressure is 200 kPa, and 55 kg/s flows into the pipe. At flange (2), the total pressure is 150 kPa. At loca- tion (3), 15 kg/s of water discharges to the atmosphere, which is at 100 kPa. Determine the total x- and z-forces at the two flanges connecting the pipe. Discuss the significance of grav- ity force for this problem. Take the momentum-flux correc- tion factor to be 1.03 throughout the pipes. m as 15 kg/s (3 3 cm 40 kg/s 10 cm ZA 55 kg/s cm FIGURE P6-77
You have entered a model rocket contest with your friend, Tiffany. You have been working on a pressurized rocket filled with nitrous oxide. Tiffany has determined the minimum atmospheric pressure at which the rocket fuel is stable. Based not hat value, and the equations given below, your task is to determine the optimum launch angle and initial velocity to maximize flight time. The goal is to re-use your rocket capsule, so you really want to avoid a fuel explosion. The atmospheric pressure varies with elevation according to the equation: P(h)= 14.7e−h/10. where p is the pressure in psi and h, is an elevation in miles above sea levels. The height (in feet) of a rocket launched at an angle α degrees with the horizontal and an initial velocity, vo in feet/second, t seconds after launch is given by the equation h(t)=-16t^2+vo*t*sin(α). 1) If Tiffany has determined that the minimum safe pressure is 11 pounds per square inch, at what altitude will the rocket explode?

Invalid path. A siphon is used to drain water from a tank as illustrated below. Assume steady flow without friction. (a) If h = 1.84 m, find the speed of outflow at the end of the siphon. m/s (b) What is the limitation on the height of the top of the siphon above the end of the siphon? Note: For the flow of liquid to be continuous, its pressure must not drop below its vapor pressure. Assume the water is at 14°C, at which the vapor pressure is 1.6 kPa.
A spherical glass particle (SG = 2.8) is allowed to settle freely in water.

In this problem you are going to use your knowledge of drag forces to estimate how long a COVID-19 infected droplet will remain in the air when exhaled. Treat the droplet as a sphere of water with a 5 μm radius. Use the size and density of water to determine the mass of the sphere. Find the terminal velocity of the droplet and, using a reasonable height, approximate the time the droplet will remain in the air.
Windmills slow the air and cause it to fill a larger channel as it passes through the blades. Consider a circular windmill with a 7-m-diameter rotor in a 10 m/s wind on a day when the atmospheric pressure is 100 kPa and the temperature is 20°C. The wind speed behind the windmill is measured at 7.5 m/s. a) Determine the diameter of the wind channel downstream from the rotor. b) Determine the mass flow rate through the wind mill. c) Determine the power produced by this windmill, presuming that the air is incompressible.
