The exhaust gas regenerator (counter-flow heat exchanger) for a gas turbine handles 1.9 kg/sec of air from its compressor and heats it by means of 2.2 kg/sec of hot exhaust gas. Exhaust gas enters the regenerator at 596°C and leaves at 312°C. Compressed air enters the regenerator at 220°C. For this temperature range a constant pressure specific heat for the exhaust has may be estimated at 1090 J/kg-°C. Assume no heat transfer other than between the generator fluids. Determine the log mean temperature difference for the exchanger, °C A. 16.98 B. 26.98 C. 36.98 D. 46.98
Heat Exchangers
Heat exchangers are the types of equipment that are primarily employed to transfer the thermal energy from one fluid to another, provided that one of the fluids should be at a higher thermal energy content than the other fluid.
Heat Exchanger
The heat exchanger is a combination of two words ''Heat'' and ''Exchanger''. It is a mechanical device that is used to exchange heat energy between two fluids.
