Unformatted text preview: 0 kPa and 77°C to 400 kPa and 327 °C. Assuming variable specific heats and neglecting the changes in kinetic and potential energies, determine (a) the isentropic efficiency of the compressor (b) the exit temperature of air if the process were reversible Note: You have to show interpolation process to get full credit. 4. A hot-water stream at 80°C enters an adiabatic mixing chamber with a mass flow rate of 4 kg/s, where it is mixed with a stream of cold water at 30°C. If the mixture leaves the chamber at 45°C, determine (a) the mass flow rate of the cold water (b) the rate of entropy generation during this adiabatic mixing process. Assume all the streams are at a pressure of 200 kPa. Due by July 21,2010 10:00AM Answers: 2. 337.6 3. (a) 66.5% (b)517.43K 4. (a)9.351 kg/s (b)0.1384kW/K...
