Final answer:
To calculate the absolute water pressure at point A in an underground pipe, use the formula P = ρgh, and plug in the known values for the density of water, gravity, and depth.
Step-by-step explanation:
To calculate the absolute water pressure at point A in an underground pipe, use the formula P = ρgh, and plug in the known values for the density of water, gravity, and depth. The question is asking to calculate the absolute water pressure at point A in an underground pipe.
The formula used to determine water pressure due to depth is P = ρgh, where P is the pressure, ρ (rho) is the density of the water, g is the acceleration due to gravity, and h is the depth below the surface. To solve for pressure (P), one must use the known values for the density of water, the acceleration due to gravity, and the depth (h) where the pressure is being calculated.
