Heat capacity rate, often denoted by the symbol \\( \\dot\{C\} \\), is a measure of the amount of heat energy required to change the temperature of a substance per unit time. It is defined as the product of the mass flow rate of a substance and its specific heat capacity. The heat capacity rate is an important concept in thermal systems and heat exchangers.
