- 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 round pipe of varying diameter carries petroleum from a wellhead to a refinery. At the wellhead, the pipe's diameter is 53.5 cm and the flow speed of the petroleum is 13.1 m/s. At the refinery, the petroleum flows at 5.25 m/s. What is the volume flow rate of the petroleum along the pipe, and what is the pipe's diameter at the refinery? volume flow rate: m³/s diameter: cmBuoyancy In the buoyancy lab, you find that the buoyant force is equal to 2.50 N.
