A well-insulated turbine operating at steady state develops 23 mw of power for a steam flow rate of 40 kg/s. the steam enters at 360°c with a velocity of 35 m / s and exits as saturated vapor at 0.06 bar with a velocity of 120 m / s. neglecting potential energy effects, determine the inlet pressure, in bar.

You have to use the steady state of forms and, mass and energy balances in order to know the pressure of the inlet. m1 = m2 = m. Solve for the assumptions of steam flow rate, as well as the saturated vapor. Just simplify it.
