Use our online Log Mean Temperature Difference Calculator: LMTD Formula: LMTD = [ΔT1- ΔT2]/[lnΔT1 / lnΔT2 ] where ΔT1 and ΔT2 as defined below for the LMTD counter-current flow and LMTD parallel flow: LMTD Counter-current flow exchanger LMTD Parallel flow Exchanger We used the equations shown above in our calculator Log Mean Temperature Difference Calculator. Why LMTD Method is used? Generally, heat exchanger are evaluated by the following methods: Effectiveness Number of Transfer Units (ε-NTU) methods. Three-dimensional parameters: Heat Capacity Rate ratio (HCRR), effectiveness and the Number of the transfer. Logarithmic Mean Temperature Difference (LMTD). The most commonly known method described…
