Figure 2: Two-stage Compressor [use $0\mathrm{deg}\mathrm{C}=273\mathrm{K}$ ] A two-stage compressor in a gas turbine brings atmospheric air at $100\mathrm{kPa}$ and $17\mathrm{deg}\mathrm{C}$ to 500 $\mathrm{kPa}$ and then cools it in an intercooler to $27\mathrm{deg}\mathrm{C}$ at constant $\mathrm{P}$. The second stage brings the air to $1000\mathrm{kPa}$. Assume that both stages are adiabatic and reversible. Find a. the combined specific work of the two-stage compressor [12] b. Find the total specific work for the case of no intercooler (i.e. one compressor from 100 to $1000\mathrm{kPa})$ [8] c. Calculate the percentage reduction in the compression work when using such a two-stage compressor with intercooling [5]
