Consider the system shown in the figure. If a change of P kPa in the pressure of air causes the brine-mercury interface in the right column to drop by d mm in the brine level in the right column while the pressure in the brine pipe remains constant, determine the ratio of A2/A1. P(kPa) = 35 d(mm) = 7 Area A₁ Air Mercury SG-13.56 Area A Brine pipe SG-1.1,
