What is the height of the water in a vacuum column when the atmospheric pressure is Po = 1.1 atm? Given: density of water is 1,000 kg/m3; 1.0 atm = 1.01 x 105 Pa; g = 9.8 m/s². O 10 m O 11 m O 77 cm O 1.1 m
The following data was obtained: atmospheric pressure: 752 torr water vapor pressure: 22 torr height of water column: 158 mm Calculate the partial pressure of the dry gas. Density of mercury if 13.6 g/cm3 and assume the desnity of the solution is 1.00 g/cm3/
QUESTION 20 A pressure that will support a column of Hg to a height of 263 mm would support a column of water to what height? The density of mercury is 13.6 g/cm°; the density of water is 1.00 g/cmº. O 358 cm 144 cm O 276 cm O 377 cm O 187 cm
19. The gauge pressure of a gas is -15 mm Hg at a point where atmospheric pressure is 760 mmHg. What is the absolute pressure for this gas? How do you understand for -20 mm Hg as a pressure unit? 20. Three different liquids are used in the following manometer. 1 Calculate pressure the differential pressure P1-P2 (D/P) in kPa if the desnity of Fluid A is 0.70 g/cm² ,the density of Fluid B is 1.00 g/cm3 and the density...
An ethanol - propanol solution is to be separated in a plate rectification column at atmospheric pressure. The feed, of which is 50 mole percent vapor, contains 40 mole percent ethanol. 98 % of the ethanol should be recovered in the top product, which should be 95 % pure by mole. The column is provided with a total condenser and a kettle-type reboiler. If the feed rate is 200 kmol/h and the reflux ratio is set at 1.7 times its...
1. A student reads a barometer in the laboratory and finds the prevailing atmospheric pressure to be 699 mm Hg. Express this pressure in atmospheres, kilopascals, torrs, pounds per square inch, and pascals. Hint: 1 atm = 101.3 kPa = 760 torr = 760 mm Hg = 14.69 psi = 1.013×105 Pa mm Hg atm kPa torr psi Pa 699 2. An automobile tire is inflated to a pressure of 29.2 psi. Express this pressure in atmospheres, kilopascals, inches Hg,...

What is height in m of a column of water when the applied pressure on the other arm of a J tube sealed at one end is 2665.1 hPa? The density of water at 20.00 0C is 0.998 g cm-3. The acceleration of gravity is 9.80665 m s-2.
The atmospheric pressure varies proportionally from sea level to height, and the air temperature drops by 6K for every T km increase (a) Draw a cylindrical volume that is height inside the atmosphere, and then calculate the pressure change and expression (dP/dy-pg) depending on the height. (b) obtain the temperature change of the atmosphere accordingto the height y(km) in the place where the sea level (y-0) is at ToK temperature. (c) obtain a barometric equation which allows for the change...
