\r\n Consider an object that is submerged in a fluid. The object experiences pressure due to weight of the fluid above it.\r\n Pressure experienced by an object submerged in a fluid at rest is called hydrostatic pressure.\r\n
\r\n\r\n The magnitude of hydrostatic pressure experienced by an object submerged in a fluid depends upon\r\n the density of the fluid and the depth.\r\n
\r\n $$P = \\rho g h$$\r\n where \\(\\rho\\) is the density of the fluid, \\(g\\) is the acceleration due to gravity and \\(h\\) is the depth.\r\n

\r\n Billy is an environmental scientist specializing in the study of icebergs.\r\n He wants to measure the depth of an iceberg.
\r\n He doesn't have a measuring tape or rope that is long enough to span the depth.
\r\n He recalls that hydrostatic pressure \\(P =\\rho g h\\).
\r\n He already knows the density of water is \\(\\rho = 1000 \\text{ kg/m}^3\\).
\r\n He figures out that if he measures the pressure P at the depth\r\n of the iceberg, he can use it calculate the depth of the iceberg as \\(h = P/\\rho g \\).\n
