Computes kG,
the 'global mass-transfer coefficient' in a cooling tower,
kG ≅ L cL ⁄
(ρ Z a) × (Integral of Merkel equation)
([Ludwig, 1997]).
The data are given from either:
a) an uploaded 'csv' file; or
(without the file) b) the 'csv' data inserted in
the textarea. Thus, if (in 'a)') a file is uploaded,
the data in the textarea are ignored.
The screen data (above) lead to #.
Typical uploadable 'csv' file: file (giving #.
