EXAMPLE. Compute the atmospheric pressure on a day when the height of the barometer is 76.0 cm. The height of the mercury column, from Eq. (16-6), depends on p and g as well as on the atmospheric pressure. Hence both the density of mercury and the local acceleration of gravity must be known. The density varies with the tem- perature, and g with the latitude and elevation above sea level. All accurate barometers are provided with a thermometer and with a table or chart from which corrections for temperature and elevation can be found. If we assume g = 980 cm/sec2 and p = 13.6 gm/cm3, %3D

The water in a tank is Oil pressurised by air, and the pressure is measured by a multi- fluid manometer as shown. The AIR tank is located on a mountain at WATER an altitude of 1400m where the 2 atmospheric pressure is 85.6kPa. Determine the air pressure in the tank if h,=0.1m, h2=0.2m, and h3=0.35m. Take the densities of water, oil and mercury to be 1000kg/m³, 850kg/m³, and 13600kg/m3 respectively. h2 Mercury -

2) Ninety thousand grams of a gas (180 kg/mol) is stored in a tank at 120 kPa and 600 K. If the gas behaved ideally, determine whether the gas is polyatomic or diatomic through consideration of the approximation for the given conditions. Given: R = 0.08206 L.atm/mol.K; 1.0 atm = 1.01325 bar = 10132.5 Pa
1C.5 The virial equation of state may also be written as an expansion in terms of pressure: Z= 1 + B'p+ ... The critical constants for water, H,0, are 218.3 atm, 55.3 cm³ mol-1 and 647.4 K. Assuming that the expansion may be truncated after the second term, calculate the value of the second virial coef- ficient B'at the critical temperature. %3D
