When can the conductive thermal resistance of the tube in a heat exchanger be neglected in overall heat transfer coefficient calculation? Never When the tube is thin or the material is highly conductive When the tube is thin. When the tube material is highly conductive. Which of the following sentence(s) is/are true? We cannot calculate thermal resistance of a solid slab. Thermal resistance concept is applicable only in Cartesian or Cylindrical coordinate. We cannot calculate ther
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.
