Transfer Flux from an Open Vessel

Example 4.1 Mass Transfer Flux from an Open Vessel. Develop a MATLAB function for numerical differentiation of a function/(x) over the range [jco, jc ] with truncation error of order h. Apply this function to evaluate the unsteady-state flux of water evaporated into air at 1 atm and 25°C from the top of an open vessel. Consider the distance between water level and the open top of the vessel to be 0.1, 0.2, and 0.3 m. The flux of water vapor at a level z above the level of water is given by Bird et al. [2] ...
