Kern proposed an empirical equation derived from data on commercial exchangers: dq kern process heat transfer pdf

) between a source and a receiver is the fundamental "potential" that facilitates heat flow. dq kern process heat transfer pdf

Donald Q. Kern's remains the "gold standard" for chemical and process engineers. First published in 1950, it was the first text to transition from theoretical thermodynamics to applied engineering, providing the rigorous calculation methods still used today to design industrial heat exchangers.
