Please use property tables. Thank you Steam enters the high-pressure turbine of an ideal reheat Rankine cycle at 10 MPa and 500°C. The low-pressure turbine inlet admits steam at 1 Mpa. Assume that the pump inlet is a saturated liquid at 10 kPa and that 80 MW of power is produced overall. 1. Report the amount of heat added in the reheat process, in kJ/kg, to one decimal place using rounding. 2. Report the amount of work produced in the low-pressure turbine, in kJ/kg, to one decimal place using rounding.
A thermal power plant operates on a regenerative cycle with a single open feed water heater, as shown in the figure. For the state points shown, the specific enthalpies are h1 =2800 kJ/kg and h2 =200 kJ/kg. The bleed to the feed water heater is 20% of the boiler steam generation rate. The specific enthalpy at state 3 is
Read the questions carefully before answering. Box or indicate your final answers when solving and draw your diagrams cleanly or use correction tape/fluid. Use the steam tables provided and DO NOT ROUND the values from the steam table. Use 4 decimal places when solving and use 2 decimal places for final answers only. Draw the TS diagram with proper placement and label of points when required. An Actual Rankine Engine receives steam at 10 MPa and 350C. The steam expands adiabatically to a pressure of 100 kPa with quality of 85%, and then condenses at the same pressure. Find the Indicated thermal efficiency, Brake Steam Rate, Combined Heat Rate, and electrical power produced if 2.12 kg/s of steam flowsin the cycle.
