If two identical pressure gauges are at the same elevation and the water levels in two tanks are the same, how will the readings compare?

When two identical pressure gauges are installed at the same elevation and are measuring the pressure of water in two tanks that have equal water levels, the readings on both gauges will be the same. This is due to the principle that pressure at a given height of a fluid in a static system is uniform, assuming no other influencing factors such as temperature variation, fluid density changes, or additional pressure inputs.

In this scenario, since both gauges are at the same height and the water levels are identical, the hydrostatic pressure exerted by the column of water above each gauge is also identical. Therefore, they will accurately reflect the same pressure reading, confirming that the conditions for both gauges are consistent. Thus, the reasoning supports that both gauges will read the same pressure under these circumstances, affirming the correctness of the chosen answer.
