Two-stage compressor with irreversibilities You need to build a two-stage compression system with intercooling to increase the pressure of Argon (monatomic gas, constant specific heat) from $$p_1=1.0$$ bar, $$T_1=280\mathrm{K}$$ to $$p_2=20$$ bar. For this purpose, you have a low-pressure compressor $$(\mathrm{L})$$ compressing from $$p_1$$ to $$p_{\mathrm{m}}$$ and a high-pressure compressor $$(\mathrm{H})$$ compressing from $$p_m$$ to $$p_2$$. The compressors have isentropic efficiencies $${?}_{\mathrm{L}}=0.91$$ and $${?}_H=0.88$$, respectively. An intercooler (IC) is used to cool the gas to $$285\mathrm{K}$$ before it enters the high-pressure compressor. Assuming the intermediate pressure $$p_{\mathrm{m}}=4.77\mathrm{bar}$$, determine the power demand of the system when the mass flow is $$1\mathrm{kg}/\mathrm{s}$$. Draw $$p?v$$ and $$T$$-s diagrams and a sketch of the process.
