What is the formula to calculate static pressure based on static head?

The formula to calculate static pressure based on static head is derived from the principle of hydrostatics, which states that the pressure at a certain depth in a fluid column is proportional to the height of the fluid column above it. Specifically, water pressure increases by approximately 0.433 psi for every foot of water depth. Thus, the correct formula reflects this relationship: static pressure is equal to the static head multiplied by 0.433 psi per foot.

This value is significant in water treatment and distribution systems, as it helps operators understand how pressure changes with varying water levels. Understanding this relationship is crucial for effective system design and operation, ensuring adequate pressure is maintained throughout the water supply network.
