SUMMARY
The diameter of a manometer does not affect the pressure at the bottom of the column when the liquid's mass, density, and gravitational field strength remain constant. The height difference in the liquid levels is determined solely by the density of the liquid and the vertical distance to the surface. This principle holds true regardless of the tube's diameter, except in cases where capillary action becomes significant in very narrow tubes. Therefore, the liquid level difference remains consistent across different tube gauges.
