- The entrance opening of a horizontal pipe has a radius of 6 cm and water is flowing at .35 m/s. The pressure at opening is 18.5 n/m2 and changes to 23.0 N/m2 at the exit. What is the area of the exit opening?Please help thank you!A submarine is stranded on the bottom of the ocean with its hatch 25 m below the surface. In this problem, assume the density of sea water is 1.03 × 103 kg/m3. Calculate the force, in newtons, needed to open the hatch from the inside, given it is circular and 0.55 m in diameter. The air pressure inside the submarine is 1.00 atm.
