A hurricane is a tropical storm formed over the ocean by low atmospheric pressure. As a hurricane
approaches land, inordinate ocean swells with a very high tides accompany the hurricane. Normally for a
hurricane, there is an "eye" located at the center with very low wind velocity. Figure Q2a depicts a
hurricane hovering over the ocean swell below. The atmospheric pressure at the point 1, generally normal
for the ocean, which is located 300 km from the eye is 10 m in mercury (Hg). At point 1, the winds are calm.
Given that the density of seawater and mercury is 1023.6 kg/m3 and 13534 kg/m3 , respectively, and the
density of air at normal sea level temperature and pressure to be 1.22 kg/m3.
i. Apply a proper form of energy conservation principle and estimate the ocean swells at the eye of the
hurricane at point 3 (h1) and point 2 (h2). Please note that the wind velocity at the eye of the hurricane
(point 3) is very low and the wind velocity at point 2 is 70 m/s. List down all the…
The bends during flight. Anyone who scuba dives is advised not to fly within the next 24 h because the air mixture for diving can introduce nitrogen to the bloodstream. Without allowing the nitrogen to come out of solution slowly, any sudden air-pressure reduction (such as during airplane ascent) can result in the nitrogen forming bubbles in the blood, creating the bends, which can be painful and even fatal. Military special operation forces are especially at risk. What is the magnitude of the change in pressure on such a special-op soldier who must scuba dive at a depth of 19 m in seawater one day and parachute at an altitude of 7.5 km the next day? Assume that the average air density within the altitude range is 0.84 kg/m3.
Suppose blood is pumped from the heart at a rate of 4.5 L/min into the aorta of radius 1.2 cm.
Determine the speed of blood through the aorta, in centimeters per second. V?

However, the movement of blood is difficult to monitor directly. Instead, some medical devices use the Hall effect, taking advantage of the fact that the blood flowing through a vein contains a considerable number of free ions. В h Model the vein in a patient's arm to be of rectangular cross section, as shown in the figure, with a width w = 4.00 mm and height h = 3.65 mm. The entire section of the vein is immersed in a constant magnetic field of B = 0.0955 T, pointing horizontally and parallel to the width. A medical device constantly monitors the resulting Hall voltage. Suppose that medical precautions mandate that the speed of the blood flow for this particular component of the body should never drop below 15.80 cm/s. At what minimum Hall voltage VH, in millivolts, should the medical device be designed to trigger an alarm to the medical staff? VH = mVarrow_forward
- 。 A common belief is that a hole in a jet plane can suck a person out. On an episode of a popular TV series, the hosts attempted to determine whether this is possible. According to the hosts' experiment, such an event cannot happen. Did they need to perform the experiment? As a science adviser to the show, the hosts ask you to perform a crude calculation to test the myth. A typical jet plane travels at 508 mph at a cruising altitude of 25500 ft.
