What is the force exerted on a piston with an area of 10 square inches at a fluid pressure of 800 psi?

To determine the force exerted on a piston, you can use the equation that relates pressure, force, and area:

Force = Pressure × Area.

In this scenario, the pressure is given as 800 psi (pounds per square inch), and the area of the piston is 10 square inches.

Using the formula:

Force = 800 psi × 10 square inches = 8000 pounds.

This calculation shows that the force exerted on the piston is 8000 pounds, which corresponds to the correct answer. The relationship between pressure and force is fundamental in fluid mechanics, clearly illustrating how applied pressure on an area translates into a tangible force affecting the piston.
