Consider the system shown in the figure below. If a change of 0.7 kPa in the pressure of air causes the glycerin-mercury interface in the right column to drop by 5 mm in the glycerin (S.G. = 1.26) level in the right column while the pressure in the glycerin pipe remains constant, the ratio of A2/A1 is _____. (Answer up to two decimal places)
    Correct answer is '0.14'. Can you explain this answer?

    Consider the system shown in the figure below. If a change of 0.7 kPa...
    Start with air pressure (point A) and move along the tube by adding (as we go down) and subtract (as we go up) until we reach the glycerin (point B) and set the result equal before and after the pressure change of air.
    where ΔhHg and Δhgly are changes in the differential mercury and glycerin column heights, respectively. The volume of mercury is constant
    By substituting the values in equation (i), we get
    From this, A2 / A1 = 0.14.
