Determine the work output-isentropic efficiency of the cycle

Assignment Help Mechanical Engineering
Reference no: EM13709108

In a reheat rankine cycle, steam enters the turbine at 4 MPa and 400 C. After expanding to 400 kPa, the steam is reheated again to 400 C, and expands in the low pressure turbine to 10 kPa. If the efficiency of the turbine and the pump is 100% and there is no friction loss, please determine the work output, isentropic efficiency of the cycle, back work ration, and draw and label the T-s diagram.
