Question
In MATLAB code
A barometer is used to measure atmospheric pressure and is filled with a high-density fluid. 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 = hpg. Find the height to which the liquid column will rise for pressures from 0 to 100 kPa for two different barometers. Assume the first uses mercury, with a density of 13.56 g/cm^3 (13,560 kg/m^3) and the second uses water, with a density of 1.0 g/cm^3 (1000 kg/m^3). The acceleration due to gravity is 9.81 m/s^2. Before you start the calculation, be sure to check your units in this calculation. The metric measurement of pressure is a pascal (Pa), equal to 1 kg/ms^2. A kPa is 100 times as big as a Pa. Your answer should be a two-dimensional matrix. (use meshgrid)
