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...
If the barometric pressure is 107.4 kPa, what is the pressure in kPa of the gas in the open end mercury manometer shown at right? (in the picture the atm pressure > gas pressure, and the height difference is 98 mm)
What is the pressure of the gas in this mercury manometer if h= 75 mm and the atmospheric pressure is 747 mmHg? What is the pressure of the gas in this mercury manometer if h = 75 mm and atmospheric pressure is 747 mmHg? pressure: mmHg gas
10. Assuming the air pressure Midland, Texas is 710. mmHg, calculate the pressure 1of the gas in a manometer in Midland, Texas. Gas 420 mmHg CHALLENGE PROBLEMS: 1. A 20. m long gas pipeline made out of Schedule 40. PVC pipe that is 2.66 cm in diameter is used to transport butane to a residential house's stove. The pipe can withstand 9928.45 kPa at 23 °C. Determine the maximum mass of gas the pipe can hold. A paintball gun's air-tank...
