The greatest ocean depths on the Earth are found in the Marianas Trench near the Philippines, where the depth of the bottom of the trench is about 11.0 km. Calculate the pressure due to the ocean at a depth of 10.5 km, assuming sea water density is constant all the way down. (The validity of the assumption of constant density is examined in one of the integrated concept problems.) atm

The maximum depth recorded for a deep-sea dive is 308 m. Assuming that (i) the density of seawater is constant at 1.03 x 103 kg/m3 and (ii) the atmospheric pressure is 101 kPa, calculate the gauge pressure at this depth (in Pa and kPa).

A hurricane force wind of 230 km/h blows across the face of a storefront window.  Estimate the force on the 2.0 m X 3.0 m window due to the difference in air pressure inside and outside the window. Assume the store is airtight so the inside pressure remains at 1.0 atm.  Express your answer to two significant figures and include the appropriate units.

ECIDO Consider a liquid (p = 1 kg/m³,) in a large bottle. It flows through a rather thin tube and come out of the tube at D. The cross-sectional area of the tube at C is c = 0.2 m², while all other parts have a cross-sectional area b = 0.1 m². The atmospheric pressure is Po= 105 Pascal, and the gravitational acceleration is g = 9.8 m/sec². Assume that the bottle is so large that the motion of the liquid at A is negligible. (hA = 50 m, hB = 10 m, hp = 30 m). A Пл 1) 2) 3) he a B 0 по What is the pressure PD at D? What is the speed VD of the liquid at D? Assuming a continuous liquid flow in the tube, what is the pressure at C?

A fusiform aneurysm bulges or balloons out an artery on all sides (pictured below). If this aneurysm occurs in an aorta, the internal radius may increase from r₁ = 1.1 cm in the normal, healthy section to 12= = 2.2 cm in the diseased section (while staying at the same vertical height). The speed of blood m flow is v₁ = 0.42 in the normal section and the gauge pressure P₁ is 99.98 mmHg. The density of 1 S blood is 1060 kg m³ Fusiform Aneurysm Image from: http://www.okclipart.com/Fusiform-Aneurysm-Clip-Art30koqyaskv/ (a) Calculate the speed of blood v2 in the aneurysm. Answer to two significant figures. Think: What equations dictating the flow through the valve are valid, equation of continuity, Bernoulli or Poiseuille? What simplifications should you make regarding the blood flow. m V₂ = S (b) Calculate the pressure gradient AP = P aneurysm healthy aorta from the healthy aorta into the aneurysm. Think: What equations dictating the flow through the valve are valid, equation of…
