Given: An existing steam power plant has the following data: It operates on a three stage regenerative cycle. The steam enters the turbine at 14 MPa and 550°C Extraction Pressures for feed water heating are the following: 2.5 MPa for a closed feed water heater 700 kpa for an open feed water heater and 150 kPa for another open feed water heater The turbine exhausts at 15 kPa. If the the condensate from the closed feed water heater is throttled to the open heater next to it and if the plant capacity is 750 MW, find the following: 1. Schematic diagram of the plant 2. T-S diagram 3. Enthalpies of the steam at the different state points 4. The mass fractions extracted for feed water heating, m.. m2, m3 5. The mass flow rate of the steam in kg/sec 6. The heat supplied in KW 7. The fuel flow rate in kg/sec if the fuel has a heating value of 35,000 kJ/kg 8. The heat rejected in the condenser in kW 9. The cycle thermal efficiency

Atmospheric air at 15 °C, relative humidity 10%, is too hot and also too dry. An air conditioner must deliver air at 21 °C and 50% humidity relative in the amount of 3600m³/h. Propose a scheme to achieve this, find the amount of liquid (at 20°C) required to be added or removed and any transfer of heat.
