Question 1 50 Points In The System Below Steam Is Supplied At 7 Mpa The System Is Adjusted So That 10 Of The Maxim 1 (49.33 KiB) Viewed 125 times

Question 1 (50 points): In the system below, steam is supplied at 7 MPa. The system is adjusted so that 10% of the maximum steam flow rate is extracted before the first turbine and another 60% of the maximum steam flow rate is then extracted at 500 kPa before the second turbine. Both lines of extracted steam are sent to an open process heater that supplies heating to campus buildings. The condenser pressure is 6 kPa. The fluid that leaves the process heater and the condenser is each pumped back to the maximum pressure and combined in a mixing unit. It is then sent back to the boiler. The mass flow rate through the boiler is 15 kg/s. Several enthalpy values are given to save you time: h1 = 2073.0 kJ/kg, h2 = 137.75 kJ/kg, h5 = 3411.4 kJ/kg, h6 = 2735 kJ/k, h9 = 640 kJ/kg, h10 = 647 kJ/kg Calculate the resulting net power produced in MW. Calculate the heat transfer to the boiler in MW. 5 WT Wrz am 7 Process Heater 7 Q Process Wpi Mixing 4 2 Wpz
