- 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.An outdoor, rectangular pool on campus is 4.5 meters [m] in width and 7.5 meters [m] in length. You may assume the depth of the pool is constant. If the pool is filled with pure water, the total pressure probe at the bottom of the pool reads 16.5 pound-force per square inch [psi]. What is the volume of the water in the pool in units of kiloliters [kL]? Length Force Mass Pressure 1 ft=12 in 1 N=0.225 lbf 1 kg=2.205 lbm 1 atm=101325 Pa 1 in=2.54 cm 1 slug = 14.5939 kg 1 atm=14.7 psi 1 m=3.28 ft Density of water=1000 kg/m3 Surface pressure=1 atmThe Earth's atmosphere at sea level and under normal conditions has a pressure of 1.01x105 Pa, which is due to the weight of the air above the ground pushing down on it. How much force due to this pressure is exerted on the roof of a building whose dimensions are 10.2 m long and 14.5 m wide?
