lib.utilities module¶
- lib.utilities.representacion(number, fmt=0, total=0, decimales=4, eng=False, tol=5, signo=False, thousand=False)[source]¶
Function for string representation of float values
- Parameters:
- numberfloat
number to transform
- fmtmode
0 - fixed point 1 - Significant figures 2 - Engineering format
- totalinteger
total number of digits
- decimalesinteger
decimal number
- engboolean
Use engineering repr for big or small number
- tolinteger
Exponent limit to use engineering repr over float normal repr
- signoboolean
Show sign, use to force positive sign
- thousandboolean
Use thousand separator point
- Returns:
- reprstr
String representation
Examples
>>> import math >>> representacion(math.pi, signo=True) '+3.1416'
- lib.utilities.colors(number, mix='', scale=False)[source]¶
Function to generate colors
- Parameters:
- number: integer
Number of required colors
- mixstr
Name color for mix

List with color hexadecimal code
- lib.utilities.exportTable(matrix, fname, ext, title=None)[source]¶
Save data to a spreadsheet file
- Parameters:
- matrixlist
array with data to save
- extstr

list with column title
- lib.utilities.spreadsheetColumn(index)[source]¶
Procedure to convert index column in AAA spreadsheet column namestyle
- Parameters:
- indexinteger
index of column start with 0
- Returns:
- keystr
column letter code, ej: A, C
Examples
>>> spreadsheetColumn(5) 'F' >>> spreadsheetColumn(75) 'BX'
- lib.utilities.formatLine(config, section, name)[source]¶
Return a matplotlib line formatting kw
- Parameters:
- configconfigparser.Configparser instance
configuration
- sectionstr
Section name in Configparser
- namestr
Line name prefix
- Returns:

- lib.utilities.SimpleEq(Tc, T, coef)[source]¶
Common procedure for calculation of simple properties like the ancillary equation for vapor pressure, saturated densities of liquid and vapor
The procedure define several equations:
\[\frac{x}{x_r} = 1 + \sum_i N_i\theta^{t_i}\]\[\ln\left(\frac{x}{x_r}\right) = \sum_i N_i\theta^{t_i}\]\[\ln\left(\frac{x}{x_r}\right) = \frac{T_c}{T}\sum_i N_i\theta^{t_i}\]\[\theta = 1 - \frac{T}{Tc}\]The coef must define the parameters:
eq: Index of equation to use
n: Polinomial parameter
t: Exponent of tita
- Parameters:
- Tcfloat
Critical Temperature, [K]
- Tfloat
Temperature, [K]
- coef: dict
Coefficient for correlation
