A U-tube differential manometer connected to a pipe shows a deflection where the mercury level in the left limb connected to point A is higher than the right limb open to the atmosphere. If the calculations yield a negative pressure relative to the atmosphere, determine the gauge pressure (in kN/m2) at point A. Assume specific weight of water is 9810 N/m3 and specific gravity of Hg is 13.6, with a standard calculated magnitude of 19.15.
