Consider the system shown in Fig. P3–57. If a change of 0.9 kPa in the pressure of air causes the brine-mercury interface in the right column to drop by 5 mm in the brine level in the right column while the pressure in the brine pipe remains constant, determine the ratio of A2/A1.
The fluid levels in a multi-fluid U-tube manometer change as a result of a pressure drop in the trapped air space. For a given pressure drop and brine level change, the area ratio is to be determined. Assumptions 1 All the liquids are incompressible. 2 Pressure in the brine pipe remains constant. 3 The variation of pressure in the trapped air space is negligible. Properties The specific gravities are given to be 13.56 for mercury and 1.1 for brine. We take the standard density of water to be Ew =1000 kg/m3. Solution: 13 inne Pipe Arel, 1. SO 1.1 AR-5 mm MCHULY SG-36 Arca, 4.
