In a heat engine, water vapor flows into a turbine and then it enters a condenser for rejecting thermal energy. The system requires maintaining the gauge pressure of the steam at 1400 kPa at the turbine inlet and at a vacuum of 71 cmHg in the condenser. Having that the barometric pressure is measured as 77.2 cmHg, calculate the absolute pressures (in kPa) of the steam at the turbine inlet and in the condenser. (Density of mercury is 13600 kg/m3)
