The flow (kg/s) is constant. In the physical model we use power, not energy. To calculate energy, we just multiply power by time. The kinetic power is what changes, just because the velocity does, E = 1/2 G (V1-V2)^2, where G is the flow. The power that generate the turbine is just because the...

That was the problem :redface:. What a stupid mistake! Thank you very much!

Hello, I have a little problem. I´ve calculated the fundamental matrix of a EDO system, such that: M(t) = P * exp( J*t) where J is a diagonal matrix: J = [-3 , 0 ; 0 , 1] and P = [1 , 1 ; 3 , -3] The problem arise when I try to find the inverse matrix of M. What I do is this As we know the...
