Mechanisms of heat transfer

Heat transfer is an essential discipline in thermal engineering that deals with the transfer, conversion, usability, and creation of heat or thermal energy. Transfer of heat occurs through various mechanisms like conduction, convection, radiation, and change of phases. All these mechanisms have distinct characteristics, but these mechanisms can simultaneously occur in an identical system.

(English Unit) A 100-pound meat is moved to the cold storage room. During preparation for storage, the meat may warm up to 45°F. That means the meat must be cooled to 32°F before it will begin to freeze. The average latent heat of fusion amounts to about 90 Btu/lb for meat. After freezing, the meat is subcooled to the quick-freeze temperature of 14 oF. The meat has a specific heat below and above freezing point of 0.7 and 0.4 Btu/ lb-oR, respectively. Find the total heat removed from cooling BTU.
