From experimental data, computes k_Ga, the 'global mass-transfer coefficient' in a cooling tower, with a the area of its (uniform) cross section, k_Ga ≅ L c_L ⁄ (ρ Z) × (Integral of Merkel equation).

The data are given from a 'csv' file, inserted in the textarea.

A typical uploadable 'csv' file: file.

# NOT USED Draws a plot of the various values of the coefficient from experimental data.
