4. A barometer (see Figure 2) is used to measure atmospheric pressure and is filled with a high- density fluid. In the past, mercury was used, but because of its toxic properties it has been replaced with a variety of other fluids. The pressure, P, measured by a barometer is the height of the fluid column, h, times the density of the liquid, p, times the acceleration due to gravity, g, or P = h Xp x g. This equation could be solved for the height: h =- PE Find the height to which the liquid column will rise for pressures from 0 to 100 kPa for two different barometers. Assume that the first uses mercury, with a density of 13.56 g/cm² (13,560 kg/m) and the second uses water, with a density of 1.0 g/cm³ (1000 kg/m³ ). The acceleration due to gravity is 9.81 m/s2. Before you start calculating, be sure to check the units in this calculation. The metric measurement of pressure is a pascal (Pa), equal to 1 kg/m s². A kPa is 1000 times as big as a Pa. Your answer should be a two-dimensional matrix.
