materials 0.1.5

Density, magnetic permeability etc. for a range of materials.

materials is a database of physical and chemical data, possibly with temperature dependence, of various more or less common materials. All data are given in SI units.

For example, to plot the density of various materials between 274 and 370 K you can do

import materials
import matplotlib.pyplot as plt
import numpy


T = numpy.linspace(274.0, 370.0, num=100)

rho_air = materials.air.density(T)
rho_argon = materials.argon.density(T)
rho_copper = materials.copper.density(T)
rho_water = materials.water.density(T)

plt.semilogy(T, rho_copper, label='copper')
plt.semilogy(T, rho_water, label='water')
plt.semilogy(T, rho_argon, label='argon')
plt.semilogy(T, rho_air, label='air')

plt.title('densities')
plt.xlabel('temperature (K)')
plt.ylabel('density (kg/m^3)')
plt.legend()

plt.show()
