heat exchanger heat transfer relationship The
uses the total heat transfer coefficient and the logarithmic average temperature difference to calculate the heat transfer rate.
symbols, variables and units
Q̇：W；U：W/(m²·K)；A：m²；ΔT_lm：K。
applicable conditions and boundaries
Steady state, U is approximately constant; complex flow patterns require a temperature difference correction factor.
