Isobutane expands adiabatically in a turbine from 5,000kPa and 250°C to 500kPa at the rate of 700 mol/sec. If the turbine efficiency is 0.8, what is the power output of the turbine and what is the temperature of the isobutane leaving the turbine?

An ideal Rankine cycle operates with the following design: 100 kg/s of steam enters the turbine at 30 bar and 500°C and is condensed at 0.1 bar. Determine the power produced and the efficiency of the cycle.

2, Propylene (assumed to be an ideal gas) is compressed adiabatically from 12.0 bar and 30 °C to 18 bar at the rate of 1 kg mol s''. If the compressor efficiency is 0.8, what is the power requirement of the compressor and what is the discharge temperature of the propylene? (R = 8.314 J/mol-K) a) What is the power requirement of the compressor? b) What is the discharge temperature of the propylene? [Take R ==5] CP %3D R %3D R

Case Study: Two AES exchangers in series have difficulty heating a process stream from 50°C to 90°C and cooling a hot stream from 110°C to 70°C at the same flow rate. Fortunately, an abandoned AES exchanger with four times the surface area of the two current exchangers is available, and it also has the correct material and sufficiently high design P&T, and it would fit on the plot space occupied by the present exchangers. Is replacement a good idea? Note: Please include a clear and brief description of the problem as well as the desired objectives. Outline the design constraints as well as the cost implications.
