A two stage Curtis superheated steam turbine is supplied at a stagnation pressure of 20 MPa and at a temperature of 500c from a boiler. It enters a nozzle and expands isentropically in the nozzle to a pressure of 10.13 MPa as it enters the first stage, where the mean diameter is 0.4 m. The turbine is designed to produce 320 Kw when the mass flow rate is 2 kg/s. Assume that the axial velocity is constant through both stages. Calculate the (a) nozzle angle at the inlet, (b) blade angles for both stages, (c) utilization factor and (d) rotor speed.

A gas turbine operates in an ideal Brayton cycle of which Argon is used as the working substance. During the start of the compression, the temperature of the gas is at 340 K and pressure of 500kPa. The compression process is adiabatic with gas conditions at the outlet of 650 K and 1930 kPa. The working substance is heated and entered the turbine at 1400 K and 1930kPa and expands adiabatically to 900 K and 490kPa.

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 isentropically to the…
