Should constant-pressure or constant-volume specific heats be used to calculate the heat capacity of a heat exchanger?
What is specific heat at constant volume? ? https://bbs.hcbbs.com/thread-4473562-1-1.html (Source: Haichuan Chemical Industry Forum Website)
The specific heat at constant pressure is generally used to calculate the heat capacity of heat exchangers. Specific heat at constant volume refers to the amount of heat absorbed per unit mass of material when its temperature increases by 1 degree Celsius, under constant volume conditions ； Specific heat at constant pressure refers to the amount of heat absorbed per unit mass of material when its temperature rises by 1 degree Celsius under constant pressure. In heat exchangers, heat exchange usually takes place at constant pressure; therefore, it is more appropriate to use specific heat at constant pressure. .
