The following parameters are recorded on a gas turbine test rig. Stage-1: Inlet temperature is 5000C, Inlet pressure is 650kPa. Exit gas pressure 150kPa. Determine the exit gas temperature for isentropic process. Stage-2 Gas is again heated to 4500C by constant volume process. Assume R=287 J/kg.K; Determine the heat added to the gas assuming Cp/Cv=1.4 and Cp/Cv=1.3; Draw the T-S diagram for the above process.
(Thermodynamics) A steady-flow system operating on the ideal Ericsson cycle can achieve the Carnot efficiency. One of the salient features of this cycle is the isothermal expansion through a heated turbine, as shown in Fig. a. Heat is added to the turbine such that the outlet temperature is equal to the inlet temperature, i.e. T₁=T₂, and the overall pressure ratio for this process is rₚ=P₁/P₂. However, an isothermal expansion through a heated turbine is very difficult to achieve in practical engineering applications. An alternate approach is two use a multi-stage expansion process with reheating. In this approach, the gas expansion process is carried out in multiple stages with reheating in between each stage. Consider the two-stage turbine expansion with reheating shown in Fig. b. The gas enters the first stage of the turbine at state A1, is expanded isentropically to an intermediate pressure Pₐ₂, is reheated at constant pressure to state B1, and is expanded in the second stage…
