Heat transfer coefficients for heat exchangers

For heat transfer equipments, separate 'heat transfer coefficients' (h) can be defined for the hot and cold media of the equipment.These heat transfer coefficients can be used to describe the heat transfer on each side of the heat exchanger. In addition an 'overall heat transfer coefficient' (U) can be defined which describes the overall heat transfer occurring in the exchanger.
