0 0 votes For a heat exchanger, $\triangle T_{\text{max}}$ is the maximum temperature difference and $\triangle T_{\text{min}}$ is the minimum temperature difference between the two fluids. LMTD is the log mean temperature difference. $C_{\text{min}}$ and $C_{\text{max}}$ are the minimum and the maximum heat capacity rates. The maximum possible heat transfer $(Q_{\text{max}})$ between the two fluids is $C_{\text{min}} \text{ LMTD}$ $C_{\text{min}} \triangle T_{\text{max}}$ $C_{\text{max}} \triangle T_{\text{max}}$ $C_{\text{max}} \triangle T_{\text{min}}$ Heat Transfer gateme-2016-set3 fluid-mechanics-and-thermal-science heat-transfer heat-exchanger + – ♦Arjun 217 views answer comment Share Follow Add Sync Questions 0 reply Please log in or register to add a comment.
