Isn´t this wrong? Why does he take delta_p_th and not delta_p_act?! the formula fot the total efficency is: n_t=(delta_p_act*Q_act)/(2*pi*M*n) So we have: n_t=P_act/P_th Or am I wrong?!
Combining delta_p_th and Q_act makes absolutly no sense in my opinion!
Isn't this all wrong?
Can someone explain the process of iteration here ? Id be thankfull
