The efficiency of the turbine is 50%.
The given parameters:
The kinetic energy of the turbine which is the input energy is calculated as follows;
E(in) = 3000 - (750 + 750)
E(in) = 1500 J
The efficiency of the turbine is calculated as follows;
[tex]E_f_f = \frac{E_{(out)}}{E_{(in)}} \times 100\%\\\\E_f_f = \frac{750}{1500} \times 100\%\\\\E_f_f = 50 \%[/tex]
Thus, the efficiency of the turbine is 50%.
