Question

Quizplus · Accepted Answer

This statement is true. The relationship between water depth and pressure is commonly referred to as the "hydrostatic pressure gradient" and is often expressed as 0.433 psi/ft of depth (or 9.80665 kPa/m for metric units). This means that for every one foot increase in water depth, there is a corresponding increase in pressure of 0.433 pounds per square inch (psi).
