हीड्रास्टाटिक दबाव किसी द्रव में संतुलन की स्थिति में किसी दिए गए बिंदु पर गुरुत्वाकर्षण बल के कारण लगाया गया दाब। सतह से गहराई के अनुपात में यह दाब बढ़ता है, क्योंकि ऊपर से नीचे की ओर बल लगाने वाले द्रव का भार बढ़ता जाता है। इसका सूत्र है [latex]p = rho gh[/latex], जहाँ [latex]rho[/latex] द्रव का घनत्व है।

The principles of hydrostatic pressure were explored by Simon Stevin in the late 16th century, who demonstrated the hydrostatic paradox—that the pressure at the bottom of a container depends only on the height of the fluid, not the shape of the container or the total weight of the fluid. This concept was a significant advance from Archimedes’ earlier work on buoyancy. The formula [latex]p = \rho g h[/latex] quantifies this relationship, where [latex]p[/latex] is the hydrostatic pressure (gauge pressure, not including atmospheric pressure at the surface), [latex]\rho[/latex] is the fluid density, [latex]g[/latex] is the acceleration due to gravity, and [latex]h[/latex] is the height of the fluid column above the point of measurement. This linear relationship means that for every 10 meters of depth in water, the pressure increases by approximately one atmosphere. This has profound implications for deep-sea exploration, where submersibles must be engineered to withstand crushing forces. The same principle governs atmospheric pressure, although the calculation is more complex because air is a compressible gas, and its density ([latex]\rho[/latex]) is not constant with altitude. Hydrostatic equilibrium is a key concept in astrophysics, describing the balance between gravity pulling inward and a pressure gradient pushing outward that keeps stars and planets stable.
