What is the greatest average speed v of blood flow at 37°C in an artery of radius 2.00 mm if the flow is to remain laminar? Take the density of blood to be 1025 kg/m³, and the viscosity to be 2.084 x 10-3 Pa-s. 1.016 m/s What is the corresponding flow rate Q? 1.276 ×10-2 m'/s 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 542 mph at a cruising altitude of 26500 ft. The windows on a jet plane measure 14.0 in x 14.0 in. Calculate the force F exerted on such a window as the plane flies at 26500 ft above the sea level. Assume the density and pressure of air at 26500 ft are 0.530 kg/m³ and 361 mbar, respectively, but that the interior of the plane remains pressurized to atmospheric pressure, 1 atm. lb Calculate the fractional difference between this force and the weight wman of a typical adult male (185 lb).
