SPND - Spundungsdruck

This is a solver-program to calculate the carbonization pressure according to this formula:

                                          2617.25
                          (- 10.73797) + ----------
                                         t + 273.15
 c(p, t) := (p + 1.013) %e                          10

c: CO₂ concentration in g/l
p: Carbonization gauge pressure in bar
ϑ: Temperature in °C
