solve equations with units

[prfpeste]

Hi,

if I solve an equation including units, I get an error message.

The code is:
p_1=1bar
T_1=20°C|K
T_2=200°C|K
k=1.4
f(x) = (x/p_1)^((k-1)/k)-T_2/T_1
p_2 = $Find{f(x) @ x = 0 : 10^10}

The error message is:
Error in "p_2 = $Find{f(x) @ x = 0 : 10^10}" on line [6]: Inconsistent units: "ht^(-0.29)·m^0.29·s^0.57 - unitless".

Is there an option to overcome this issue?

For empirical equations you need to convert it to unitless units as T_2/T_1 is unitless

Hi!

Maybe x must be also in "bar" units? Then you can write:
p_2 = $Find{f(x) @ x = 0bar : 10^10bar}

It works in this way.

cool, thanks for the fast response!
