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,...

In principle many different liquids could be used in a barometer. Mercury is usually preferred by virtue of its low vapour pressure and high density. As part of a school project, you have decided to build a barometer using water. Assuming the maximum pressure that the instrument will need to read is 1.05 atm, determine the height of the column required if (a) you ignore the vapour pressure of water or (b) you take the vapour pressure of water (PH2O=3.17...

To determine the height of a building the pressure is measured at ground level and at the top. The pressure at the top is x=98 kPa and at ground level is y=101 kPa. Assuming air density constant and equal to 1.2 kg/m², and the acceleration of gravity g=9.8 m/s2, estimate the height of the building. Give your answer in meters. REQUIRED RELATIVE ACCURACY +/-0.196
