An engineer designed a double pipe heat exchanger where the hot fluid (cp=2400 J/kg.K) enters at a temperature of 100 °C with a flowrate of 0.1 kg/s and is wanted to leave at a temperature of 60 °C. On the other hand, the cold fluid (cp=1200 J/kg.K) enters the heat exchanger at a temperature of 30 °C with a flowrate
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.
An engineer designed a double pipe heat exchanger where the hot fluid (cp=2400 J/kg.K) enters at a temperature of 100 °C with a flowrate of 0.1 kg/s and is wanted to leave at a temperature of 60 °C. On the other hand, the cold fluid (cp=1200 J/kg.K) enters the heat exchanger at a temperature of 30 °C with a flowrate of 0.2 kg/s and is wanted to be heated up to 70 °C. Show that whether this design is realistic or not. If yes, what is the flow configuration (i.e. counter or parallel flow)?
