Some Notes About Manometry (ME 33 Handout, prepared by Professor J. M. Cimbala) The elevation difference z in a U-tube manometer does not depend on the following: 1. Tube diameter (provided that the tube diameter is large enough that capillary effects are negligible). In the sketch below, for a given pressure in the tank, z is the same in manometers A and B, even though the tube diameter of manometer B is larger than that of manometer A. Note that the amount of manometer liquid in each of the U-tube manometers has been adjusted such that the level of the interface between fluids 1 and 2 on the left side of each manometer is at the same elevation, for direct comparison. P atm Pressure chamber A ρ 2 1 z z Manometer B Manometer C Tee z Manometer D z Manometer A Explain why in the space below. 2. Tube length (provided that the tubes are long enough to include elevation difference z ). In the sketch, z is the same in manometers A and C, even though manometer C is shorter than manometer A. Explain why
