Question

Ideal Rankine

An ideal Rankine reheat cycle operates with a boiler pressure of 7 MPa, a condenser pressure of 10 kpA and the reheat section at 800 kPa Both the high pressure and low pressure turbines exhaust stem (turbine exists "4" and "6") with a quality of 93%. Determine the temperatures at the inlet of each turbine. Determine the work done by each turbine. Determine the thermal efficiency of the system. An ideal Rankine Cycle operates with a high pressure of 7 MPa and a Condenser pressure of 10 kPa your manager is considering whether or not one or two reheat steps might be added to the system in an attempt to increase the net work output and the thermal efficiency of the system. You have been asked to analyze the system under THREE different operating scenarios as follows. Scenario 1: NO REHEAT step (existing basic Rankine cycle). Scenario 2 : ONE reheat step at a pressure of 2.0 MPa. Scenario 3 : TWO reheat steps at 2 & 3 using scenario 1 as a baseline.
