Final answer:
To calculate the pressure difference between two points with a 2-meter height difference, the formula P = ρgh is used, considering the acceleration due to gravity as 9.8 m/s². The density value (ρ) is needed for exact calculations.
Step-by-step explanation:
The pressure difference between two points in a pipe can be determined using the formula P = ρgh, where P is the pressure, ρ is the density of the fluid, g is the acceleration due to gravity, and h is the height difference between the points.
In this case, the height difference is given as 2 meters. By substituting the given values into the formula, we can find the pressure difference between the two points.
To determine the pressure difference between two points in a pipe when the height difference is 2 meters, we use the formula P = ρgh, where P represents pressure, ρ (rho) denotes the density of the fluid, g is the acceleration due to gravity, and h is the height difference.
Given that the acceleration due to gravity g is 9.8 m/s², the pressure difference ΔP can be calculated as ΔP = ρgΔh. Without the specific value for the fluid's density, we cannot compute an exact number, but the relationship is direct: as the height difference or density increases, so does the pressure difference.
