What is LMTD Calculation in Heat Exchanger about?
This document discusses the calculation of the log mean temperature difference (LMTD) for a shell and tube heat exchanger. The experiment measured inlet and outlet temperatures for hot and cold fluids flowing in countercurrent through the exchanger. Calculations using these temperatures found the average LMTD was 7.68°C for a heating tank at 45°C and 13.58°C for 60°C heating, with less than 4% difference from theoretical values. The larger the LMTD, the greater the heat transfer between the fluids.
