- A submersible vehicle is in ocean at a depth of 26.2 m. What is the absolute pressure (in Pa) at this depth? The density of the water in the ocean is 1.00 X 103 kg/m³, and the air above is at a pressure of 101.3 kPa. Submit your answer in exponential form.A medical technician is trying to determine what percentage of a patient's artery is blocked by plaque. To do this, she measures the blood pressure just before the region of blockage and finds that it is P₁, while in the region of blockage it is P2. Furthermore, she knows that blood flowing through the normal artery just before the point of blockage is traveling at v₁, and the density of this patient's blood is p. The patient is laying down so there are no differential effects due to gravity. a. Symbolically, what is the ratio of the artery radius at the blockage, r2, to the ratio of the artery radius at the blockage, r₁? (find r₂/r₁) b. Find the numerical value of r2/r1.
