4.7 A barometer (see Figure P4.7) 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, tmes the acceleration due to gravity, g or This equation could be solved for the height: 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/cm3 (13,560 kg/m3) and the second uses water, with a density of 1.0 g/cm3 (1000 kg/m3). The acceleration due to gravity is 9.81 /s2. Before you start calculting, be sure to check the units in this calculation. The metric measurement of pressure is a pascal (P), equal to l kg/ms2 A kPa is 1000 times as big as a Pa. Your answer should be a two dimensional matrix
