Homework Help: The Gauge Pressure

  1. Jan 27, 2005 #1
    Can someone please attempt this problem?

    A tall cylinder with a cross-sectional area of 12.0 cm^2 is partially filled with mercury; the surface of the mercury is 5 cm above the bottom of the cylinder. Water is slowly poured in on top of the mercury and the two fluids don't mix. What volume of the water must be added to double the gauge pressure at the bottom of the cylinder.

    Can some please write step-by-step solution, not just the answer?

    Thank you
