LMTD stands for Logarithmic Mean Temperature Difference and is formulated as,LMTD = {(∆T - ∆t) / ln(∆T/∆t)}, where ∆T and ∆t amount to the temperature difference between the fluids at both the ends of the Heat Exchanger. The temperature change that takes place across the Heat Exchanger is not linear - it is exponential. LMTD is also a parameter used to determine the heat transfer rate through the Heat Exchanger. As the LMTD increases, the heat transfer speeds up.

Mechanical Power Transmission
Power transmission is a process required in almost every piece of machinery. From the tiny motors in pop-up selfie cameras to the innovative transmission lines of the Large Hadron Collider, power transmission applications are all around us. We use power transmission methods to transmit power from the prime mover to the driven machinery for its function. There are four main types of power transmission – mechanical, electric, hydraulic and pneumatic. In this article,
