Expert Answer

Seawater has a density of about 1000 kg/m^3. You have given the depth (height = 7.50 km or 7500 m), and we know the acceleration due to gravity is 9.81 m/s^2. 1000 kg/m^3 * 7500 m * 9.81 m/s^2 = 7.3 x 10^7 kg/m/s^2 or 7.3 x 10^7 Pa.

Question

How do I calculate fluid pressure water in flowing rivers?

Community Answer

P= Density * Gravity * Height. Multiply the density by the gravitational force and then multiply by the height.

Question

Are air- and water-pressure gauges different?

Community Answer

Yes, they are different. Air pressure gauges use a Bourdon tube, while water pressure gauges use a media for measurement.

Question

How do I calculate the fluid pressure of a hydraulic system?

Community Answer

You can calculate hydraulic system pressure using an equation, which states that pressure in pounds per square inch equals force in pounds times the surface area of a piston in square inches. Obtain the values to make the calculation. You will need to know the force in pounds (F) and surface area of the piston in square inches (A).
