Two pressure sensors are located at the seafloor: one is 100 m and the other is 500 m off the coastline. For a wave train of 10-s period, the pressure sensor closer to the shoreline measures the pressure amplitude as 5911 Pa and the other sensor measures the pressure amplitude as 4987 Pa. Given that the wave height is H = 1.5 m, what is the average bathymetric slope between the two pressure sensors? Assume that the wave height has negligible variation between the two observation points. Take the magnitude of the gravitational acceleration as 9.81 m/s2 and the density of the seawater as 1000 kg/m3.

Q.2. When an oblique shock strikes a solid wall, it reflects as a shock of sufficient strength to cause the exit flow M3 to be parallel to the wall, as in the figure. For airflow with M1 = 2.5 and p1 = 100 kPa, compute M3, p3 and the angle Ø. M2 M, = 2.5 M3 40°
Humans evolved in Earth's atmosphere, therefore the pressures interior to the body are relatively close to atmospheric pressure. Because the differences between internal body pressures and atmospheric pressure are so small, individuals have a difficult time gauging the magnitude of atmospheric pressure. Suppose an individual is lying on his stomach with sheets of paper stacked on his back. If each sheet of paper has a mass of 0.00360 kg and is the standard letter size of 8.5 in by 11 in (0.216 m by 0.279 m), how many sheets must be stacked to produce a pressure on his back equal to atmospheric pressure (roughly 101325 Pa)? sheets of paper required:

The lower section of a constricted pipe has a diameter of 8 cm. The upper section of the pipe, located 0.1 m above the lower section, has a diameter of 3 cm. The pressure at the lower section is 2.1 ×× 104 Pa, while the pressure in the upper section is 1 ×× 104 Pa. Assuming water moves through the pipe in a steady flow, calculate the speed (in m s-1) of the flow in the lower section. The density of water is 1000 kg m-3
