1) 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 pi 1.0 bar, T = 280 K to p2 = 20 bar. For this purpose, you have a low-pressure compressor (L) compressing from p1 to pm and a high-pressure compressor (H) compressing from pm to p2. The compressors have isentropic efficiencies L = 0.91 and H = 0.88, respectively. An intercooler (IC) is used to cool the gas to 285 K before it enters the high-pressure compressor. Assuming the intermediate pressure pm = 4.77 bar, determine the power demand of the system when the mass flow is 1 kg/s. Draw p-v and T-s diagrams and a sketch of the process.
