Small differences in gas pressures are commonly measured with a micro-manometer of the type illustrated in Fig. (3). This device consists of two large reservoirs each having a cross sectional area A, which are filled with a liquid having a specific weight Y1 and connected by a U-tube of cross-sectional area A, containing a liquid of specific weight y2. When a differential gas pressure, P, - P2 , is applied, a differential reading, h, develops. It is desired to have this reading sufficiently large (so that it can be easily read) for small pressure At differentials. Determine the relationship between h and P1 P, when the area ratio is small, and show Ar that the differential reading, h, can be magnified by making the difference in specific weights, Y2 - Y1 , small. Assume that initially (with P = 2P2). %3D P1 P2 Y1 Figure (3)
