Heat transfer does not occur randomly.It is driven. In every process plant, heat moves because certain physical conditions exist. These conditions create a driving force — the reason heat starts…
A simple temperature difference, ΔT, feels intuitive. Hot in minus cold out seems like a reasonable way to describe how strongly heat transfer is driven. In real process equipment, however,…
LMTD — Log Mean Temperature Difference — is one of the most widely used concepts in heat exchanger design and analysis. It appears simple in formula form, yet it is…
Understanding that heat transfer occurs is only the beginning.Every real engineering decision depends on how much heat is transferred, how fast, and where. Those decisions begin with understanding the required…
