Problem 45

Small differences in gas pressures are commonly measured with a micromanometer of the type illustrated in Fig. P2.45. This device consists of two large reservoirs each having a crosssectional area Ar which are filled with a liquid having a specific weight 1 and connected by a U-tube of cross-sectional area At containing a liquid of specific weight 2. When a differential gas pressure p1 p2, is applied, a differential reading, h, develops. Itis desired to have this reading sufficiently large (so that it can beeasily read) for small pressure differentials. Determine the relationshipbetween h and p1 p2 when the area ratio At/Ar is small, andshow that the differential reading, h, can be magnified by makingthe difference in specific weights, 2 1, small. Assume that initially(with p1 p2) the fluid levels in the two reservoirs are equal.2.
