What is the formula for pressure?

Pressure is defined as the amount of force applied per unit area. The correct formula for pressure is derived from this definition, which is expressed mathematically as the force exerted divided by the area over which that force is distributed. Therefore, when calculating pressure, you take the total force acting on a surface and divide it by the area of that surface.

This concept is fundamental in various applications within power engineering, as understanding pressure is crucial for the safe and efficient operation of boilers, pipelines, and other systems that operate under pressure. Accurate calculations of pressure help ensure proper equipment sizing, safety margin assessments, and overall system performance.

The other options do not represent the relationship correctly; for instance, multiplying force by area or adding the two does not yield a measure of pressure, and dividing area by force would not provide a meaningful physical quantity in terms of pressure.
