1. The initial pressure reading on an ocean-faring submarine is 105 kPa at a depth of 0.35 m. The submarine descends and the new pressure reading is 125 kPA. At what depth is the submarine now located? The density of seawater is 1023 kg/m3 .
1B. The area of a hose on the left end is 3.5 x10-3 m3 while the area on the right end of the hose is 3.0 x 10-3 m3 . A liquid will travel a constant 10 cm in 400 ms on the left end of the hose. What will be the velocity of the liquid as it exits the right end of the hose? Assume a constant density.
I know we are only to post one at a time, but I really need help with both of these, I will rate!! Please explain answers fully, so that I may rework and understand. Thank you!

1. A submarine dives from the surface of the ocean to a depth of 3500 feet ( 1foot= 0.305 meters) . a) what pressure increase does the submarine experience? b) at this depth of 3500 feet, what is the force (in units of N) on the hatch which has an area of 0.6 m2 ? Take the density of sea water to be 1030 kg/m3 ( It is a good assumption to presume that sea water has essentially constant density,...
(a) Calculate the absolute pressure at an ocean depth of 150 m. Assume the density of sea water is 1 022 kg/m3 and the air above exerts a pressure of 101.3 kPa?? Pa (b) At this depth, what is the buoyant force on a spherical submarine having a diameter of 4.80 m? N
1. A bathyscaphe is at a depth of 6 km in the ocean. What is the pressure on it assuming density of ocean water to be 1024 kg/mA3? At a given instant, the blood pressure in the heart is 1.6 x 10^4 Pa. If an artery in the brain is 0.45 m above the heart, what is the pressure in the artery? Ignore any pressure changes due to blood flow. Density of blood is 1060 kg/mA3. 2. I 3. A...
