Heat & Mass ch 1
Introduction and Basic Concepts
Term | Definition |
---|---|
Heat Transfer | Energy in transit due to a difference in temperature |
Specific Heat (c) | The energy required to raise the temperature of a unit of mass of a substance by one degree [kJ/Kg*K, Btu/lbm*R, kJ/Kg*C, Btu/lbm*F] |
Three Modes of Heat Transfer | Conduction Convection Radiation |
Conduction | Heat transfer from the more energetic particles of a substance to the adjacent less energetic ones as a result of direct interaction between the particles - therm Engy transfer directly thru matter - happens within s, l, or g when temp diff are present |
Fourier's Law of Hr |
