Question

Required information NOTE: This is a mart question. Once an answer is submitted yox ww be we to run to this part Conskler a steam power plant that operates on a reheat Rankine cycle and has a nel power output of 80 MW. Steam enters the high pressure turbine at 10 MPa and 500'C and the low pressure turbine at 1 MPa and 500°C. Steam leaves the condenser as a saturated liquid at a pressure of 10 kPa. The stropelickincy of the turbine is 82 percent and that of the pump is 95 percent Determine the quality for temperature, if superheated of the steam at the torine exit Use steam tables. You must provide an answer before moving on to the next part) The temperature of the steam at the turbine exitis
