EXAMPLE 6-2 Using a Manometer to Measure Gas Pressure When the manometer in Figure 6-5(c) is filled with liquid mercury (d = 13.6 g/cm"), the barometric pressure is 748.2 mmHg, and the difference in mercury levels is 8.6 mmHg. What is the gas pressure Pgas? Analyze We must first establish which is greater: the barometric pressure or the gas pressure. In Figure 6-5(c), the baro- metric pressure forces liquid mercury down the tube toward the gas sample. The barometric pressure...

Problems in Fluid Pressure and Pressure Force 1. AU-tube manometer with mercury is connected to two points on an inclined pipe carrying water. There is an elevation difference of 4ft between the lower and upper points. If the mercury level difference between the two sides of the manometer is 20.3 inches, what is the pressure at the lower point in the pipe, if the pressure at the upper point is 17.5 psi? 2. A vertical semicircular disc of 2 m...
