What is static pressure in vertical pipe 10 mtrs with SG 0.8 and pipe 1 square inch?

Static pressure in a vertical pipe can be calculated using the formula ( P = \rho \cdot g \cdot h ), where ( P ) is the pressure, ( \rho ) is the density of the fluid, ( g ) is the acceleration due to gravity (approximately ( 9.81 , \text{m/s}^2 )), and ( h ) is the height of the fluid column. For a specific gravity (SG) of 0.8, the density ( \rho ) of the fluid is ( 0.8 \times 1000 , \text{kg/m}^3 = 800 , \text{kg/m}^3 ). Thus, the static pressure at a height of 10 meters would be ( P = 800 , \text{kg/m}^3 \times 9.81 , \text{m/s}^2 \times 10 , \text{m} = 78480 , \text{Pa} ) or approximately 78.5 kPa. The cross-sectional area of 1 square inch does not affect the static pressure calculation directly, as static pressure is independent of pipe diameter.
